Here are some general guidelines for writing references:

• Follow the citation style guidelines: Different disciplines and journals may require different citation styles (e.g., APA, MLA, Chicago). It is important to follow the specific guidelines for the citation style required.
• Include all necessary information : Each citation should include enough information for readers to locate the source. For example, a journal article citation should include the author(s), title of the article, journal title, volume number, issue number, page numbers, and publication year.
• Use proper formatting: Citation styles typically have specific formatting requirements for different types of sources. Make sure to follow the proper formatting for each citation.
• Order citations alphabetically: If listing multiple sources, they should be listed alphabetically by the author’s last name.
• Be consistent: Use the same citation style throughout the entire paper or project.
• Check for accuracy: Double-check all citations to ensure accuracy, including correct spelling of author names and publication information.
• Use reputable sources: When selecting sources to cite, choose reputable and authoritative sources. Avoid sources that are biased or unreliable.
• Include all sources: Make sure to include all sources used in the research, including those that were not directly quoted but still informed the work.
• Use online tools : There are online tools available (e.g., citation generators) that can help with formatting and organizing references.

Purpose of References in Research

References in research serve several purposes:

• To give credit to the original authors or sources of information used in the research. It is important to acknowledge the work of others and avoid plagiarism.
• To provide evidence for the claims made in the research. References can support the arguments, hypotheses, or conclusions presented in the research by citing relevant studies, data, or theories.
• To allow readers to find and verify the sources used in the research. References provide the necessary information for readers to locate and access the sources cited in the research, which allows them to evaluate the quality and reliability of the information presented.
• To situate the research within the broader context of the field. References can show how the research builds on or contributes to the existing body of knowledge, and can help readers to identify gaps in the literature that the research seeks to address.

Importance of References in Research

References play an important role in research for several reasons:

• Credibility : By citing authoritative sources, references lend credibility to the research and its claims. They provide evidence that the research is based on a sound foundation of knowledge and has been carefully researched.
• Avoidance of Plagiarism : References help researchers avoid plagiarism by giving credit to the original authors or sources of information. This is important for ethical reasons and also to avoid legal repercussions.
• Reproducibility : References allow others to reproduce the research by providing detailed information on the sources used. This is important for verification of the research and for others to build on the work.
• Context : References provide context for the research by situating it within the broader body of knowledge in the field. They help researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
• Evaluation : References provide a means for others to evaluate the research by allowing them to assess the quality and reliability of the sources used.

Advantages of References in Research

There are several advantages of including references in research:

• Acknowledgment of Sources: Including references gives credit to the authors or sources of information used in the research. This is important to acknowledge the original work and avoid plagiarism.
• Evidence and Support : References can provide evidence to support the arguments, hypotheses, or conclusions presented in the research. This can add credibility and strength to the research.
• Reproducibility : References provide the necessary information for others to reproduce the research. This is important for the verification of the research and for others to build on the work.
• Context : References can help to situate the research within the broader body of knowledge in the field. This helps researchers to understand where their work fits in and how it builds on or contributes to existing knowledge.
• Evaluation : Including references allows others to evaluate the research by providing a means to assess the quality and reliability of the sources used.
• Ongoing Conversation: References allow researchers to engage in ongoing conversations and debates within their fields. They can show how the research builds on or contributes to the existing body of knowledge.

Use the DOI number for the source whenever one is available. DOI stands for "digital object identifier," a number specific to the article that can help others locate the source. In APA 7, format the DOI as a web address. Active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list. Also see our Quick Answer FAQ, "Can I use the DOI format provided by library databases?"

Jerrentrup, A., Mueller, T., Glowalla, U., Herder, M., Henrichs, N., Neubauer, A., & Schaefer, J. R. (2018). Teaching medicine with the help of “Dr. House.” PLoS ONE , 13 (3), Article e0193972. https://doi.org/10.1371/journal.pone.0193972

For journal articles that are assigned article numbers rather than page ranges, include the article number in place of the page range.

Article (Without DOI)

Found in a common academic research database or in print.

Casler , T. (2020). Improving the graduate nursing experience through support on a social media platform. MEDSURG Nursing , 29 (2), 83–87.

If an article does not have a DOI and you retrieved it from a common academic research database through the university library, there is no need to include any additional electronic retrieval information. The reference list entry looks like the entry for a print copy of the article. (This format differs from APA 6 guidelines that recommended including the URL of a journal's homepage when the DOI was not available.) Note that APA 7 has additional guidance on reference list entries for articles found only in specific databases or archives such as Cochrane Database of Systematic Reviews, UpToDate, ProQuest Dissertations and Theses Global, and university archives. See APA 7, Section 9.30 for more information.

Found on an Open Access Website

Eaton, T. V., & Akers, M. D. (2007). Whistleblowing and good governance. CPA Journal , 77 (6), 66–71. http://archives.cpajournal.com/2007/607/essentials/p58.htm

Provide the direct web address/URL to a journal article found on the open web, often on an open access journal's website. In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

Weinstein, J. A. (2010).  Social change  (3rd ed.). Rowman & Littlefield.

If the book has an edition number, include it in parentheses after the title of the book. If the book does not list any edition information, do not include an edition number. The edition number is not italicized.

American Nurses Association. (2015). Nursing: Scope and standards of practice (3rd ed.).

If the author and publisher are the same, only include the author in its regular place and omit the publisher.

Lencioni, P. (2012). The advantage: Why organizational health trumps everything else in business . Jossey-Bass. https://amzn.to/343XPSJ

As a change from APA 6 to APA 7, it is no longer necessary to include the ebook format in the title. However, if you listened to an audiobook and the content differs from the text version (e.g., abridged content) or your discussion highlights elements of the audiobook (e.g., narrator's performance), then note that it is an audiobook in the title element in brackets. For ebooks and online audiobooks, also include the DOI number (if available) or nondatabase URL but leave out the electronic retrieval element if the ebook was found in a common academic research database, as with journal articles. APA 7 allows for the shortening of long DOIs and URLs, as shown in this example. See APA 7, Section 9.36 for more information.

Poe, M. (2017). Reframing race in teaching writing across the curriculum. In F. Condon & V. A. Young (Eds.), Performing antiracist pedagogy in rhetoric, writing, and communication (pp. 87–105). University Press of Colorado.

Include the page numbers of the chapter in parentheses after the book title.

Christensen, L. (2001). For my people: Celebrating community through poetry. In B. Bigelow, B. Harvey, S. Karp, & L. Miller (Eds.), Rethinking our classrooms: Teaching for equity and justice (Vol. 2, pp. 16–17). Rethinking Schools.

When a text has been republished as part of an anthology collection, after the author’s name include the date of the version that was read. At the end of the entry, place the date of the original publication inside parenthesis along with the note “original work published.” For in-text citations of republished work, use both dates in the parenthetical citation, original date first with a slash separating the years, as in this example: Freud (1923/1961). For more information on reprinted or republished works, see APA 7, Sections 9.40-9.41.

Classroom Resources

Citing classroom resources.

If you need to cite content found in your online classroom, use the author (if there is one listed), the year of publication (if available), the title of the document, and the main URL of Walden classrooms. For example, you are citing study notes titled "Health Effects of Exposure to Forest Fires," but you do not know the author's name, your reference entry will look like this:

Health effects of exposure to forest fires [Lecture notes]. (2005). Walden University Canvas. https://waldenu.instructure.com

If you do know the author of the document, your reference will look like this:

Smith, A. (2005). Health effects of exposure to forest fires [PowerPoint slides]. Walden University Canvas. https://waldenu.instructure.com  

A few notes on citing course materials:

• [Lecture notes]
• [Course handout]
• [Study notes]
• It can be difficult to determine authorship of classroom documents. If an author is listed on the document, use that. If the resource is clearly a product of Walden (such as the course-based videos), use Walden University as the author. If you are unsure or if no author is indicated, place the title in the author spot, as above.
• If you cannot determine a date of publication, you can use n.d. (for "no date") in place of the year.

Note:  The web location for Walden course materials is not directly retrievable without a password, and therefore, following APA guidelines, use the main URL for the class sites: https://class.waldenu.edu.

Dictionary Entry

Merriam-Webster. (n.d.). Leadership. In Merriam-Webster.com dictionary . Retrieved May 28, 2020, from https://www.merriam-webster.com/dictionary/leadership

When constructing a reference for an entry in a dictionary or other reference work that has no byline (i.e., no named individual authors), use the name of the group—the institution, company, or organization—as author (e.g., Merriam Webster, American Psychological Association, etc.). The name of the entry goes in the title position, followed by "In" and the italicized name of the reference work (e.g., Merriam-Webster.com dictionary , APA dictionary of psychology ). In this instance, APA 7 recommends including a retrieval date as well for this online source since the contents of the page change over time. End the reference entry with the specific URL for the defined word.

Online Video/Webcast

Walden University. (2013).  An overview of learning  [Video]. Walden University Canvas.  https://waldenu.instructure.com  

Use this format for online videos such as Walden videos in classrooms. Most of our classroom videos are produced by Walden University, which will be listed as the author in your reference and citation. Note: Some examples of audiovisual materials in the APA manual show the word “Producer” in parentheses after the producer/author area. In consultation with the editors of the APA manual, we have determined that parenthetical is not necessary for the videos in our courses. The manual itself is unclear on the matter, however, so either approach should be accepted. Note that the speaker in the video does not appear in the reference list entry, but you may want to mention that person in your text. For instance, if you are viewing a video where Tobias Ball is the speaker, you might write the following: Tobias Ball stated that APA guidelines ensure a consistent presentation of information in student papers (Walden University, 2013). For more information on citing the speaker in a video, see our page on Common Citation Errors .

Taylor, R. [taylorphd07]. (2014, February 27). Scales of measurement [Video]. YouTube. https://www.youtube.com/watch?v=PDsMUlexaMY

For videos from streaming sites, use the person or organization who uploaded the video in the author space to ensure retrievability, whether or not that person is the speaker in the video. A username can be provided in square brackets. As a change from APA 6 to APA 7, include the publisher after the title, and do not use "Retrieved from" before the URL. See APA 7, Section 10.12 for more information and examples.

Technical and research reports by governmental agencies and other research institutions usually follow a different publication process than scholarly, peer-reviewed journals. However, they present original research and are often useful for research papers. Sometimes, researchers refer to these types of reports as gray literature , and white papers are a type of this literature. See APA 7, Section 10.4 for more information.

Reference list entires for TED Talks follow the usual guidelines for multimedia content found online. There are two common places to find TED talks online, with slightly different reference list entry formats for each.

TED Talk on the TED website

If you find the TED Talk on the TED website, follow the format for an online video on an organizational website:

Owusu-Kesse, K. (2020, June). 5 needs that any COVID-19 response should meet [Video]. TED Conferences. https://www.ted.com/talks/kwame_owusu_kesse_5_needs_that_any_covid_19_response_should_meet

The speaker is the author in the reference list entry if the video is posted on the TED website. For citations, use the speaker's surname.

TED Talk on YouTube

If you find the TED Talk on YouTube or another streaming video website, follow the usual format for streaming video sites:

TED. (2021, February 5). The shadow pandemic of domestic violence during COVID-19 | Kemi DaSilvalbru [Video]. YouTube. https://www.youtube.com/watch?v=PGdID_ICFII

TED is the author in the reference list entry if the video is posted on YouTube since it is the channel on which the video is posted. For citations, use TED as the author.

Walden University Course Catalog

To include the Walden course catalog in your reference list, use this format:

Walden University. (2020). 2019-2020 Walden University catalog . https://catalog.waldenu.edu/index.php

If you cite from a specific portion of the catalog in your paper, indicate the appropriate section and paragraph number in your text:

...which reflects the commitment to social change expressed in Walden University's mission statement (Walden University, 2020, Vision, Mission, and Goals section, para. 2).

And in the reference list:

Walden University. (2020). Vision, mission, and goals. In 2019-2020 Walden University catalog. https://catalog.waldenu.edu/content.php?catoid=172&navoid=59420&hl=vision&returnto=search

Vartan, S. (2018, January 30). Why vacations matter for your health . CNN. https://www.cnn.com/travel/article/why-vacations-matter/index.html

For webpages on the open web, include the author, date, webpage title, organization/site name, and URL. (There is a slight variation for online versions of print newspapers or magazines. For those sources, follow the models in the previous sections of this page.)

American Federation of Teachers. (n.d.). Community schools . http://www.aft.org/issues/schoolreform/commschools/index.cfm

If there is no specified author, then use the organization’s name as the author. In such a case, there is no need to repeat the organization's name after the title.

In APA 7, active hyperlinks for DOIs and URLs should be used for documents meant for screen reading. Present these hyperlinks in blue and underlined text (the default formatting in Microsoft Word), although plain black text is also acceptable. Be consistent in your formatting choice for DOIs and URLs throughout your reference list.

A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Instantly correct all language mistakes in your text

Be assured that you'll submit flawless writing. Upload your document to correct all your mistakes.

Table of contents

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Harvard Referencing Guide

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

Vancouver Referencing Guide

APA referencing, used in the social and behavioural sciences, uses author–date in-text citations corresponding to an alphabetical reference list at the end.

APA Referencing Guide APA Reference Generator

MHRA referencing, used in the humanities, uses footnotes in the text with source information, in addition to an alphabetised bibliography at the end.

OSCOLA referencing, used in law, uses footnotes in the text with source information, and an alphabetical bibliography at the end in longer texts.

OSCOLA Referencing Guide

Prevent plagiarism, run a free check.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

Citation is necessary while writing your school essay, a publication, or a Master’s thesis. We all want our efforts to be acknowledged, right? The lack of references and citations can make the source think you are trying to steal their work. Hence, the question is how to go about making references.

Do you want to learn how to cite in a research paper? Then this article is for you, as it contains the details of how to reference when writing a research paper. There is a standard way to do this in educational journals and organizational publications.

Hence, a researcher must understand how to reference their writings or journals. It is another thing to write a journal properly, but crediting the sources is more crucial.

Follow this guide to learn:

• The importance of referencing and citations for your academic works;
• How to cite in APA, MLA, Chicago, IEEE, and ASA styles;
• Essential guidelines to follow for a published work.

Why Referencing and Citation Matter

Another important question is: What is the need for referencing and citation? The major reason for citations in research paper format is to serve as directional cues for the employed knowledge. When you cite, readers can know that some portions of your content belong to you. Hence, it is easier to identify how recent the information is.

Citation for your paper comes with several advantages. They include:

Academic Integrity

The citation affirms the integrity of your academic writing. In this information age, there are several details, and it can be difficult to authenticate. When you reference, it helps readers understand the necessity of the discussed topic. Referencing certain authors can give more authority to your papers.

Avoiding Plagiarism

Plagiarism refers to the mindless lifting of details from another material without acknowledging the details. For the source, they could believe you are stealing from them. In most countries, copyright infringement is a punishable crime and can make you lose your hard work.

Building Credibility

Credibility is the goal of every academic scholar. There is no better way to gain relevance than by citing sources from other credible ones.

Facilitating Further Research

For other researchers like you, providing citations can serve as other sources for more information. It helps them to know other philosophies about the subject.

Choosing the Right Citation Style

Now that the advantages have been established, the new worry is the choice of the right style. There are several styles with their respective peculiarities. For example, the MLA writing style is common in liberal scientific paper citations. Let’s delve more into MLA formatting for research papers and other styles.

APA (American Psychological Association)

The commonest style used by many scholars is APA formatting , especially if there is no stated style. This approach employs the use of in-text citations to explain the source. It’s the simplest form of citation.

Here is an in-text referencing example:

“Exercise is a good way to recover from ailments.” APA, n.d. (American Psychological Association).

The reference style includes:

• The author’s name;
• The author’s name is in parenthesis to follow the referenced excerpt;
• The publication date.

MLA (Modern Language Association)

MLA-style formation is concise and known for its scientific referencing format. The peculiarity of the MLA citation is its source citation, episode title, and document layout. You have to:

• Include the parenthetical citation;
• Create some spaces away from the left margin;
• Include the author’s or source’s name.

Ensure you capitalize every word when including the names. You can employ professional MLA Citation Generators to make the compilation easier. It is perfect for the citation format of scientific papers.

Chicago Style

Chicago’s style is famous for two things:

• The in-text citation within the paper;
• The reference list is at its end.

It is an author-date approach. Hence, the in-text citation for a research paper has the author’s or source name and publication year.

IEEE (Institute of Electrical and Electronics Engineers)

This employs the use of numbers. It is chronological as it arranges the citation based on the order of appearance. A click on it takes the reader to the full reference at the end of the paper. To make it easier, you can employ IEEE Citation Maker for a well-curated task. This way, you won’t have to worry about the manual compilation of the IEEE citation style.

This is similar to the author-date approach by Chicago Style. You can:

• Create the quotation;
• Include the parentheses for the author’s name and publication date;
• Add the page number using a colon.

Components of a Citation

Do you want to know how to complete a citation for your professional research paper writing service and research paper? Learn about its components.

The author is also regarded as the source. It is the original writer of the material you are referencing. Sometimes, there may be multiple authors. Do not miss out on anyone while citing a research paper.

Title of the Source

The title of the source is often the name given to the material by the author.

Publication Date

As the name implies, this refers to the date the source was published. Frequently, most writers include it at the start of their material. State the exact month and year of publication, separated with a comma. See example:

“(2016, March 7).”

Including the publisher’s details is only necessary for the full reference. It should be at the end of the paper. It can facilitate further research.

Page Numbers

The page number is necessary, as it helps to easily refer to different sections of the paper.

DOI (Digital Object Identifier) or URL (Uniform Resource Locator)

A DOI is a link to a resource on the internet. The resource can be a book or its chapter. On the other hand, a URL is an address that indicates where the resource can be found. It helps to locate the resource. The use of URLs and DOIs directs readers to the digital identifier of the source.

In-Text Citations

An in-text citation for a research paper is the brief form of the bibliography that you include in the body of the content. It contains the author’s family name and year of publication. It provides enough details to help users know the source in their reference list. Each citation format for research papers is unique.

See citation examples below.

How to Cite Direct Quotations for Each Citation Style

The general rule in referencing is that in-text citations must have a corresponding entry in your reference list. Let’s see how!

There are two types of APA in-text citations:

Parenthetical:

The researchers concluded, “Climate change poses significant challenges for coastal communities” (Johnson & Lee, 2021, p. 78).

In their study on the effects of exercise on mental health, Smith and Johnson (2019) found that regular physical activity was associated with a significant decrease in symptoms of anxiety and depression. According to their research, engaging in exercise three times a week for at least 30 minutes had a positive impact on participants’ overall well-being.

APA in-text citation style employs the source’s name and publication year. A direct quotation will include the page number. Remember, you can generate a citation in a research paper using the APA style via a citation generator.

MLA is known as the scientific style of citation. The uniqueness of MLA Style formatting is the use of a direct quote (in quotes), the Author’s name and page number (in parentheses).

In the novel “To Kill a Mockingbird,” Atticus Finch imparts wisdom to his children, saying, “You never really understand a person until you consider things from his point of view… until you climb into his skin and walk around in it” (Lee 30).

For Chicago, you are to include a parenthetical citation, the author’s name, the publication year, and the quote’s page number.

As Adams (2009) argues, “History is a vast early warning system” (53).

IEEE (Institute of Electrical and Electronics Engineers) style typically uses numerical citations in square brackets for in-text citations. It doesn’t rely heavily on direct quotations in the same way as some other citation styles, like APA or MLA. Instead, IEEE generally prefers paraphrasing and citing the source, but direct quotations can be used when necessary. Here’s an example of a direct quotation in IEEE style:

In-Text Citation:

As stated by Smith, “In most cases, the impedance of the transmission line remains relatively constant throughout its length” [1].

Corresponding Reference Entry:

[1] A. Smith, “Transmission Line Impedance Analysis,” IEEE Transactions on Electrical Engineering, vol. 45, no. 3, pp. 212-225, 2010.

ASA is different because it contains the author’s name, publication year, and even the page number.

According to Smith (2010), “Social institutions shape our behaviors and interactions in profound ways” (p. 45).

How to Cite Paraphrased Information

While writing a college paper, paraphrasing is important to achieve clarity, but it is ideal to cite the source of the paraphrased information. The proper way to cite paraphrased information is to include a parenthetical citation. The style of referencing for all citation styles doesn’t change, but they should be in parenthesis.

“Strength can be defined in terms of ability and acquired skills, according to (Jack et al. 2023).

Citing Multiple Authors

The technique is different when you are citing a source that has multiple authors. For the first-time citation, you should include the names of all the authors. The subsequent activities to generate a citation in APA should only include the first author’s surname and the proper use of ‘et al.’ However, you should include the surname and initials of all these authors in the full reference. Separate the authors with commas and ampersands before the final name.

Two Authors:

When a source has two authors, include both authors’ names in the in-text citation every time you reference the source. Use an ampersand (&) between the authors’ names, and include the year of publication in parentheses. For example:

(Smith & Johnson, 2020) found that…

Three to Five Authors:

When a source has three to five authors, list all authors in the first in-text citation. Use an ampersand (&) between the last two authors’ names. For subsequent citations of the same source, use only the first author’s name followed by “et al.” and the year. For example:

First citation: (Smith, Johnson, & Williams, 2018)…

Subsequent citations: (Smith et al., 2018)…

Six or More Authors:

When a source has six or more authors, you should use “et al.” in both the first and subsequent in-text citations, along with the year. For example:

(Smith et al., 2019) conducted a study on…

Group Authors:

When citing sources authored by a group, organization, or company, use the full name of the group or organization as the author in the in-text citation. If the abbreviation is well-known, you can use the abbreviation in subsequent citations. For example:

First citation: (American Psychological Association [APA], 2019)…

Subsequent citations: (APA, 2019)

When a source has two authors, include both authors’ names in the in-text citation, separated by the word “and.” For example:

(Smith and Johnson 45) found that…

Three or More Authors:

When a source has three or more authors, include only the first author’s name followed by “et al.” in the in-text citation. For example:

(Smith et al. 72) conducted a study on…

If a source has no identifiable author, use a shortened version of the title in the in-text citation. Enclose the title in double quotation marks or use italics if it’s a longer work (e.g., a book or film). For example:

(“Title of the Source” 28) argues that…

(American Psychological Association 62) states that…

Author-Date System:

In the Author-Date system, when a source has two authors, include both authors’ last names and the publication year in parentheses in the in-text citation, separated by an ampersand (&). For example:

(Smith & Johnson 2020) found that…

When a source has three or more authors, you can use “et al.” after the first author’s name in the in-text citation. For example:

(Smith et al. 2018) conducted a study on…

Notes and Bibliography System:

In the Notes and Bibliography system, when a source has two authors, include both authors’ full names in the note. For example:

John Smith and Jane Johnson, Title of the Work (Place of Publication: Publisher, Year), page number.

When a source has three or more authors, list the first author’s name followed by “et al.” in the note. For example:

John Smith et al., Title of the Work (Place of Publication: Publisher, Year), page number.

When a source has two authors, include both authors’ last names in the in-text citation, separated by the word “and.” For example:

(Smith and Johnson 2020) found that…

Three Authors:

When a source has three authors, include all three authors’ last names in the in-text citation, separated by commas. For example:

(Smith, Johnson, and Williams 2018) conducted a study on…

More than Three Authors:

When a source has more than three authors, you should use the first author’s last name followed by “et al.” in the in-text citation. For example:

(Smith et al. 2019) conducted a study on…

When a source has two authors, include both authors’ last names in the in-text citation, separated by “and.” For example:

[1] Smith and Johnson found that…

When a source has three or more authors, use the first author’s last name followed by “et al.” in the in-text citation. For example:

[2] Smith et al. conducted a study on…

Page Numbers in In-Text Citations

The use of page numbers in in-text citations is more peculiar to APA style. You can use paragraphs as indicated above if the source has no page, as seen in some e-books and websites.

Creating a Reference List or Bibliography

Creating a reference list is one of the most important tips for writing a research paper because it shows the general scheme of paper citation. This part of the content is a step-by-step process you can follow to create your reference list for your research paper.

Formatting and Organizing Your References

Formatting and organizing your references is the first step when you want to create your bibliography. You need to arrange all the full references to the in-text citation in the downward part of your paper. To avoid missing out on any, writing every full reference when you write the in-text citation is advisable.

Alphabetizing Your References

Alphabetizing your references ensures you create your bibliography in an orderly fashion for easy comprehension. Hence, you can do it numerically or alphabetically. The numerical order is dependent on the referencing system you are using, while the alphabetical order uses the author’s name to organize the reference.

Citations for Different Source Types

Different source types have their respective references, even for scientific papers. The commonest sources include books, journals, chapters, presentations, and online (to cite a website).

See how to cite an example for each source below:

Tips for Accuracy

The goal of citing your paper is because of the advantages stated above. As such, you should not negotiate the accuracy of your citation. Here are the tips you can follow for accurate referencing:

Verify Your Source

Confirm if your source is credible or not. It is easier to verify books, journal articles, and chapters. You should check multiple links to confirm their authenticity.

Follow the One Style Guide

Maintain a single referencing style throughout your paper. It is improper to employ multiple referencing styles. If not specified, you can consider the APA style.

Verify DOI and URLs

DOI and URLs can be tricky and sensitive. A simple error with the punctuation can make them invalid. Hence, verifying every DOI and URL with a click is advisable. Discrediting your citation format for a scientific research paper reference based on an invalid URL is not worth it.

Online Citation Generators

Thanks to the digital age, you don’t have to worry about manually compiling your reference or generating its in-text citation. You can employ online generators to do the rough work for you. In turn, you will have more time to focus on the major content of your research work.

Use University Libraries and Writing Centers

Libraries and writing centers have extensive collections of cited sources. Since books, publications, and journals are more credible sources, university libraries remain a valid source to increase the credibility of your paper.

Leave No Stone Unturned!

Referencing and citation are the best way to preserve the relevance of your academic paper. It gives it the appropriate credibility for future use. That means another writer can refer to your work over many years, even when the level of advancement may be unmatched. A well-referenced work is evergreen.

One must note that well-oriented research paper citations have a proper format. The options include APA, MLA (citation style for science), Chicago, IEEE, and ASA. If not stated, it is advisable to follow the APA formatting style, as it is the most common. However, stick with formatting while compiling cited sources for a research paper.

Table of Contents

Every scientific paper builds on previous research – even if it’s in a new field, related studies will have preceded and informed it. In peer-reviewed articles, authors must give credit to this previous research, through citations and references. Not only does this show clearly where the current research came from, but it also helps readers understand the content of the paper better.

There is no optimum number of references for an academic article but depending on the subject you could be dealing with more than 100 different papers, conference reports, video articles, medical guidelines or any number of other resources.

That’s a lot of content to manage. Before submitting your manuscript, this needs to be checked, cross-references in the text and the list, organized and formatted.

The exact content and format of the citations and references in your paper will depend on the journal you aim to publish in, so the first step is to check the journal’s Guide for Authors before you submit.

There are two main points to pay attention to – consistency and accuracy. When you go through your manuscript to edit or proofread it, look closely at the citations within the text. Are they all the same? For example, if the journal prefers the citations to be in the format (name, year), make sure they’re all the same: (Smith, 2016).

Your citations must also be accurate and complete. Do they match your references list? Each citation should be included in the list, so cross-checking is important. It’s also common for journals to prefer that most, if not all, of the articles listed in your references be cited within the text – after all, these should be studies that contributed to the knowledge underpinning your work, not just your bedtime reading. So go through them carefully, noting any missing references or citations and filling the gaps.

Each journal has its own requirements when it comes to the content and format of references, as well as where and how you should include them in your submission, so double-check before you hit send!

In general, a reference will include authors’ names and initials, the title of the article, name of the journal, volume and issue, date, page numbers and DOI. On ScienceDirect, articles are linked to their original source (if also published on ScienceDirect) or to their Scopus record, so including the DOI can help link to the correct article.

A spotless reference list

Luckily, compiling and editing the references in your scientific manuscript can be easy – and it no longer has to be manual. Management tools like Mendeley can keep track of all your references, letting you share them with your collaborators. With the Word plugin, it’s possible to select the right citation style for the journal you’re submitting to and the tool will format your references automatically.

Like with any other part of your manuscript, it’s important to make sure your reference list has been checked and edited. Elsevier Author Services Language Editing can help, with professional manuscript editing that will help make sure your references don’t hold you back from publication.

How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

How to Write an APA Style References Page

Last Updated: April 4, 2024 Fact Checked

This article was co-authored by Michelle Golden, PhD . Michelle Golden is an English teacher in Athens, Georgia. She received her MA in Language Arts Teacher Education in 2008 and received her PhD in English from Georgia State University in 2015. There are 13 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 920,194 times.

Once you finish writing a research paper, you will need to cite the sources you used to do your research. How you format your Works Cited page depend on the style guidelines you are required to use. The American Psychological Association (APA) citation style is primarily used in the social sciences. This format differs from the Modern Language Association (MLA) style because it emphasizes the date by placing it earlier in the citation, and it helps reduce bias by using only the last names and first initials of the author, thereby removing gender from the author’s name.

Creating APA Style References Manually

• Example of one author: Krauss, L. M. (1993).
• Example of two authors: Wegener, D. T., & Petty, R. E. (1994).
• Example of three or more authors: Kernis, M. H., Cornell, D. P., Sun, C. R., Berry, A., Harlow, T., & Bach, J. S. (1993).
• Example of more than seven authors: Miller, F. H., Choi, M. J., Angeli, L. L., Harland, A. A., Stamos, J. A., Thomas, S. T., . . . Rubin, L. H. (2009). Book title. New York, NY: Basic Books.

• Example, book: (1999).
• Example, newspaper, magazine, newsletter: (1993, June).
• Example, daily or weekly periodicals: (1994, September 28).
• Example, for a work with no date given: (n.d.)

• Italicize book titles. For example, Call of the wild.
• Do not italicize journal, newspaper, or magazine titles. Just include these as normal text. For example, “Making the grade in chemistry: A story of trial and error.”

• Example: Boston, MA: Random House.
• Example: New York, NY: Scribner.
• Example: Palmerston North, New Zealand: Dunmore Press.

• For example, ReCall instead of RECALL , and Knowledge Management Research & Practice, not Knowledge Management Research and Practice.
• Use the ampersand if the journal does, instead of spelling out the word and.

• Title of Periodical, volume number (issue number), pages referenced.
• For example, Psychology Today, 72 (3), 64-84 or The Statesman Journal , 59(4), 286-295.

• Example: Eid, M., & Langeheine, R. (1999). The measurement of consistency and occasion specificity with latent class models: A new model and its application to the measurement of affect. Psychological Methods, 4, 100-116. Retrieved from http: // www.apa.org/journals/exampleurl
• You do not need to include your date of access for APA references.

Creating APA References with an Online Generator

• Some generators require you to supply your email address and they will send you the citations. It's best to avoid these, because they may sell your information to businesses that will clog your inbox with spam.
• Many searchable library databases also provide citations in multiple styles, such as EBSCO. If you are using your university library’s databases , then you should have the option of getting an APA style citation for the source from the article’s page in the database.
• Just remember to check any references that you get from an online generator for accuracy because they may have errors.

• The auto-fill method will supply a lot of information instantly, which you will then verify to make sure it's correct.
• The manual entry method will give you a form to complete yourself, and you will enter the appropriate author names, dates, and other relevant information manually.
• Make sure to select the type of work you are citing. The BibMe generator has five main boxes: Journal, Website, Book, Video, and Other. Click on the box that corresponds to the type of work you need to cite. [12] X Research source

• For a journal, enter the title of the journal.
• For a website, enter the URL or a keyword. Generally, using the url for the source will get more accurate results.
• For a book, enter the book title, author's name, or ISBN. You can find the ISBN on the book jacket, usually next to the price and the barcode. The ISBN will provide the most complete information.
• For a video, enter the URL or a major keyword. The URL will yield more specific results.
• If you choose “Other,” you will see a long list of alternative formats to choose from. Select the one that is appropriate (e.g., Magazine Article, Blog/Podcast, Painting/Artwork), and follow the prompts to enter the publication details manually.

• If you supply specific information (such as a URL or ISBN), this will be a short list.
• If you enter less specific information (such as a keyword), you will get a longer list. Your source may or may not be included, depending on whether the generator located it. If your source is not on the list, then try supplying more specific information, or using the manual-fill entry mode.
• If you enter a common book title, then you will see a list of options. Check the author and date to be sure you're choosing the right one. For example, the book title Nemesis will return a list of 20 different books, each written by a different author.

• Your references should always include title, author, publication date, publication location, and publisher. If any of these are missing, then you'll need to refer to the work itself to find that information.

• Copy and paste the generated citation if you want to add it to your references manually.
• Continue to enter more works if you want the generator to compile an alphabetized reference list of all your references.

• Check for misspellings or glaring omissions, such as missing dates or author names.
• Check to be sure you have included every source you wanted to include.

Formatting and Ordering Your References

• Do not use bold, italics, or quotation marks on the word “References.”
• Double space the entire “References” page.
• Do not add an extra line between the title '”References” and your first reference item. [19] X Research source

• To set your indentations to hanging, open the “Paragraph” dialog box by clicking the small arrow to the right of “Paragraph” near the top of your MS Word document.
• After the box opens, look for the section called “Indentation.”
• Click on the drop down menu called “Special” that is in this section and select “Hanging.”
• Your entries will now automatically have hanging indentations.

• Alphabetize letter by letter. Remember that “nothing precedes something,” or in other words, the shorter version of two similar names should come first. For example, Brown, J. R. would come before Browning, A. R.
• Alphabetize the prefixes M', Mc, and Mac exactly as they are shown. Do not alphabetize them as if they were all spelled out (Mac).
• Ignore apostrophes in names. For example, MacNeil would come before M'Carthy.

• List one-author entries before multiple-author entries, when the first author is the same. For example, “Alleyne, R. L. (2001).” would come before “Alleyne, R. L. & Evans, A. J. (1999).”

• For example, “American Society for the Prevention and Cruelty of Animals,” not “ASPCA”.
• For example, “University of Michigan, Department of Psychology,” not “Department of Psychology, University of Michigan”.

• For example, “ Merriam-Webster's collegiate dictionary (11th ed.). (2005) Springfield, MA: Merriam-Webster."

Learning Objectives

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style, the documentation and formatting style followed by the American Psychological Association, as well as MLA style, from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract, or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred to one hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12, you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Exercise \(\PageIndex{1}\)

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Exercise \(\PageIndex{2}\)

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Exercise 1
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings”.

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings”, but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Exercise \(\PageIndex{3}\)

Working with the document you developed in Note 13.11 “Exercise 2”, begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11, the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Section 13.2 and Section 13.3 provide extensive guidelines for citing a variety of source types.

writing at work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. (Section 13.3 provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

This study aimed to evaluate the impact of APOE4 homozygosity on Alzheimer’s disease (AD) by examining its clinical, pathological and biomarker changes to see whether APOE4 homozygotes constitute a distinct, genetically determined form of AD. Data from the National Alzheimer’s Coordinating Center and five large cohorts with AD biomarkers were analyzed. The analysis included 3,297 individuals for the pathological study and 10,039 for the clinical study. Findings revealed that almost all APOE4 homozygotes exhibited AD pathology and had significantly higher levels of AD biomarkers from age 55 compared to APOE3 homozygotes. By age 65, nearly all had abnormal amyloid levels in cerebrospinal fluid, and 75% had positive amyloid scans, with the prevalence of these markers increasing with age, indicating near-full penetrance of AD biology in APOE4 homozygotes. The age of symptom onset was earlier in APOE4 homozygotes at 65.1, with a narrower 95% prediction interval than APOE3 homozygotes. The predictability of symptom onset and the sequence of biomarker changes in APOE4 homozygotes mirrored those in autosomal dominant AD and Down syndrome. However, in the dementia stage, there were no differences in amyloid or tau positron emission tomography across haplotypes, despite earlier clinical and biomarker changes. The study concludes that APOE4 homozygotes represent a genetic form of AD, suggesting the need for individualized prevention strategies, clinical trials and treatments.

How to Write a Reference Letter (Template & Examples)

By Ammar Ahmed

Published: January 29, 2024

A reference letter serves as a formal endorsement of an individual’s skills, character, and achievements, typically penned by a former employer, colleague, or academic mentor. 

This guide aims to empower professionals with the tools and knowledge to craft effective reference letters, combining best practices with practical templates to streamline this essential task.

Types of Reference Letters

Understanding the different types of reference letters is crucial for professionals, as each type caters to specific contexts and highlights various aspects of an individual’s profile. Below, we explore three key types: Professional, Academic, and Character Reference Letters.

Professional Reference Letters

Professional reference letters are written by a previous employer, supervisor, or professional colleague. They focus on the applicant’s work experience, skills, and professional achievements. These letters are often required during job applications or for career advancement opportunities. 

These letters should detail the individual’s role, responsibilities, key accomplishments, and work ethic. It’s essential to mention specific instances where the individual demonstrated their skills and contributed to the organization’s success.

Academic Reference Letters

Academic reference letters are typically requested for educational pursuits, such as college admissions, scholarships, or academic awards. Written by teachers, professors, or academic advisors, these letters highlight the individual’s academic achievements, intellectual capabilities, and potential for future success in their field of study. 

They should reflect on the individual’s academic performance, participation in class, and any notable projects or research work. This type of letter often emphasizes the individual’s dedication, curiosity, and ability to overcome academic challenges.

Character Reference Letters

Character reference letters focus primarily on the personal attributes of an individual. They are usually written by someone who knows the person well but is not a family member, such as a mentor, family friend, or community leader. 

These letters are particularly important when assessing an individual’s suitability for a role that requires a high degree of trust and integrity. They should provide insights into the individual’s character, values, and behaviors, illustrating how these traits have been beneficial in various situations.

Letter of Recommendation Examples

In crafting a letter of recommendation, it’s essential to tailor the content to the specific needs and strengths of the individual. Whether it’s for a professional role, character assessment, or a remote work position, each letter should effectively highlight the candidate’s unique qualities and contributions. 

These examples are designed to provide a clear understanding of how to articulate a candidate’s abilities and achievements in a manner that resonates with the recipient, ensuring the letter is both compelling and relevant to the candidate’s desired opportunity.

Taylor Robinson Hiring Committee Chair Innovatech Solutions 321 Future St. Techville, TV 32167 April 5, 2024

Dear Mr./Ms. Robinson,

It is with great enthusiasm that I recommend Laura Smith for the position of Project Manager at Innovatech Solutions. As the Senior Director of Project Management at TechGenius, I had the privilege of observing Laura’s professional growth and remarkable contributions over her four-year tenure as an Assistant Project Manager.

Laura’s standout achievement was her leadership in the “GreenTech Initiative” project in 2020.

What to Include in a Reference Letter

When composing a reference letter, it’s essential to include certain key elements to ensure the letter is effective and provides a comprehensive overview of the candidate’s qualifications.

These elements include:

1. Sender’s Information

The sender’s information is a critical component of any reference letter, as it establishes the credibility and authority of the person writing the letter.

This section should be clearly outlined at the top of the letter and include the following details:

• Name: The full name of the individual writing the reference letter.
• Title or Position: The professional title or position of the sender, which adds weight to the reference. This should be the current title or the one held while working with the individual being recommended.
• Company or Organization: The name of the company or organization where the sender is employed or affiliated.
• Contact Information: Including an address, phone number, and email address is crucial. It not only offers a means for the recipient to verify the information or seek further clarification but also demonstrates transparency and openness.

2. Recipient’s Information

• Name: The full name of the recipient. If the recipient’s name is not known, a general title or department can be used, such as “Hiring Manager” or “Admissions Committee.”
• Title or Position: Including the recipient’s professional title or position helps in directing the letter to the appropriate person, especially in large organizations where multiple individuals may be involved in the decision-making process.
• Company or Organization: The name of the company or organization where the recipient works. This acknowledges the professional setting into which the candidate is seeking entry or advancement.
• Address: The full postal address of the company or organization. 

3. Salutation

The salutation in a reference letter is more than just a formality; it sets the tone for the communication and shows respect for the recipient.

Here are key elements to consider:

• A Formal Greeting: Begin with a formal greeting such as “Dear,” which is universally recognized as professional and respectful.
• Addressing the Recipient: If you know the recipient’s name, use it directly after the greeting, e.g., “Dear Mr. Smith,” or “Dear Dr. Jones.” 
• Inclusive and Respectful Language: If the recipient’s name or gender is unknown, use a neutral and inclusive salutation like “Dear Hiring Manager,” “Dear Selection Committee,” or “To Whom It May Concern”. 

4. Opening Paragraph

The opening paragraph of a reference letter is pivotal in establishing the context of your relationship with the candidate and setting the stage for the endorsement to follow.

Here are some elements to include in this initial section:

• Introduce Yourself: Start by introducing yourself to give the recipient an understanding of who you are. Mention your name and your professional position or title, as this adds credibility to your recommendation.
• Your Relationship with the Candidate: Clearly state your professional or academic relationship with the person you are recommending. This could be as their supervisor, colleague, professor, or mentor.
• Duration of Relationship: Include how long you have known the individual. This time frame helps the recipient gauge the depth and extent of your experience with the candidate.
• Purpose of the Letter: Briefly mention the purpose of your letter – to recommend the individual for a specific position, program, or opportunity. This sets a clear context for the rest of your letter.

5. Body Paragraphs

The body paragraphs are the core of the reference letter, where you provide detailed insights into the candidate’s qualifications, skills, achievements, and character.

Here’s how to structure this section effectively:

• Specific Examples and Details: Use concrete examples to illustrate the person’s skills and qualifications. For instance, if you are highlighting their leadership skills, mention a specific project they led and the positive outcomes that resulted from it.
• Highlight Relevant Experiences and Accomplishments: Discuss experiences that directly relate to the position or opportunity the individual is pursuing. For example, if they’re applying for a managerial role focus on instances where they demonstrated effective management skills.
• Unique Qualities or Strengths: Point out any unique strengths or qualities that make the individual stand out. This could include exceptional problem-solving skills, innovative thinking, or a strong commitment to teamwork.
• Personal Anecdotes or Stories: Including a brief story or anecdote can make your letter more engaging and memorable. This could be an instance where the individual overcame a significant challenge or went above and beyond in their role.
• Balanced Perspective: While it’s important to focus on positive attributes, offering a balanced perspective can add authenticity to your letter. If appropriate, you can mention areas where the candidate has shown growth during your relationship.

Remember, the goal of these paragraphs is to provide a vivid picture of the candidate’s abilities and character. Well-chosen examples and stories make your endorsement more convincing and help the recipient understand why the individual is an excellent fit for the opportunity.

6. Closing Paragraph

The closing paragraph of a reference letter is where you encapsulate your overall recommendation and express your support for the individual.

Here are some elements to include:

• Summarize Key Points: Briefly restate the most important qualities, achievements, or skills of the candidate that you have highlighted in the letter. This reinforces your endorsement and reminds the reader of the candidate’s suitability for the position or opportunity.
• Express Your Strong Recommendation: Clearly state your confidence in the candidate and your belief in their suitability for the role or opportunity. Use affirmative language like, “I highly recommend,” or “I am confident that,” to leave no doubt about your support.
• Offer to Provide Further Information: Indicate your willingness to provide additional information or clarification if needed. This shows your genuine support and readiness to assist further in the candidate’s application process.
• Contact Information Reminder: Although your contact information is already at the top, a brief reminder here ensures that it is easily accessible for the reader, should they wish to follow up with you.

7. Closing Salutation

Here’s how to conclude your letter appropriately:

• Use a Professional Closing: Opt for a formal and universally accepted closing phrase. Common examples include “Sincerely,” “Best regards,” or “Yours truly.” 
• Consistency with the Tone: Ensure that the closing salutation matches the overall tone of your letter. If your letter is highly formal, a closing like “Sincerely” is appropriate. For a slightly less formal tone, “Best regards” can be a good choice.
• Space for Signature: If you are sending a hard copy or a scanned version of the letter, leave space for your handwritten signature above your typed name. This personal touch adds authenticity to the document.
• Typed Name and Title: Below the signature space, type your full name and title again.

Tips for Writing Letters of Recommendation

Crafting effective letters of recommendation requires a delicate balance of showcasing the candidate’s strengths, providing specific examples, and employing persuasive language. Here are some valuable tips to help you navigate the intricacies of this crucial task.

Quantify Achievements

When writing a letter of recommendation, it’s powerful to quantify the candidate’s achievements. Use specific figures and statistics to illustrate their accomplishments. For example, instead of saying “significantly increased sales,” specify “increased sales by 30% over six months.” This provides concrete evidence of their capabilities and makes their achievements more tangible and credible. Quantifying contributions also helps the recipient gauge the scale and impact of these accomplishments, offering a clearer picture of the candidate’s potential.

Connect to the Position or Opportunity

Tailor the letter to the specific position or opportunity the candidate is applying for. Highlight skills and experiences that are directly relevant to the job requirements or academic program. For instance, if the candidate is applying for a leadership role, emphasize their successful team management experiences. This shows that you understand what the role entails and have thoughtfully considered how the candidate’s skills and experiences make them a good fit, making your recommendation more relevant and persuasive.

Include Keywords

Identify important terms in the job listing or academic program description, such as “project management,” “analytical thinking,” or “creative problem-solving,” and weave them into your letter. This not only tailors the letter to the specific role but also ensures it passes through any automated screenings, increasing the chance that your recommendation will be read by decision-makers.

Leverage Technology for Reference Letter Management

Utilize technology platforms for efficient reference letter management. For example, online reference request platforms simplify the process of requesting, writing, storing, and submitting letters of recommendation. These tools often offer templates, reminders, and the ability to submit letters directly to institutions or employers. 

Leveraging such technology can streamline the process, ensuring timely submission and organization of your reference letters, while also offering a secure way to manage sensitive personal information contained within these documents.
