How to Write a Bibliography for a Research Paper

Do not try to “wow” your instructor with a long bibliography when your instructor requests only a works cited page. It is tempting, after doing a lot of work to research a paper, to try to include summaries on each source as you write your paper so that your instructor appreciates how much work you did. That is a trap you want to avoid. MLA style, the one that is most commonly followed in high schools and university writing courses, dictates that you include only the works you actually cited in your paper—not all those that you used.

• If your assignment calls for a bibliography, list all the sources you consulted in your research.
• If your assignment calls for a works cited or references page, include only the sources you quote, summarize, paraphrase, or mention in your paper.
• If your works cited page includes a source that you did not cite in your paper, delete it.
• All in-text citations that you used at the end of quotations, summaries, and paraphrases to credit others for their ideas,words, and work must be accompanied by a cited reference in the bibliography or works cited. These references must include specific information about the source so that your readers can identify precisely where the information came from.The citation entries on a works cited page typically include the author’s name, the name of the article, the name of the publication, the name of the publisher (for books), where it was published (for books), and when it was published.

The good news is that you do not have to memorize all the many ways the works cited entries should be written. Numerous helpful style guides are available to show you the information that should be included, in what order it should appear, and how to format it. The format often differs according to the style guide you are using. The Modern Language Association (MLA) follows a particular style that is a bit different from APA (American Psychological Association) style, and both are somewhat different from the Chicago Manual of Style (CMS). Always ask your teacher which style you should use.

A bibliography usually appears at the end of a paper on its own separate page. All bibliography entries—books, periodicals, Web sites, and nontext sources such radio broadcasts—are listed together in alphabetical order. Books and articles are alphabetized by the author’s last name.

Most teachers suggest that you follow a standard style for listing different types of sources. If your teacher asks you to use a different form, however, follow his or her instructions. Take pride in your bibliography. It represents some of the most important work you’ve done for your research paper—and using proper form shows that you are a serious and careful researcher.

Bibliography Entry for a Book

A bibliography entry for a book begins with the author’s name, which is written in this order: last name, comma, first name, period. After the author’s name comes the title of the book. If you are handwriting your bibliography, underline each title. If you are working on a computer, put the book title in italicized type. Be sure to capitalize the words in the title correctly, exactly as they are written in the book itself. Following the title is the city where the book was published, followed by a colon, the name of the publisher, a comma, the date published, and a period. Here is an example:

Format : Author’s last name, first name. Book Title. Place of publication: publisher, date of publication.

• A book with one author : Hartz, Paula.  Abortion: A Doctor’s Perspective, a Woman’s Dilemma . New York: Donald I. Fine, Inc., 1992.
• A book with two or more authors : Landis, Jean M. and Rita J. Simon.  Intelligence: Nature or Nurture?  New York: HarperCollins, 1998.

Bibliography Entry for a Periodical

A bibliography entry for a periodical differs slightly in form from a bibliography entry for a book. For a magazine article, start with the author’s last name first, followed by a comma, then the first name and a period. Next, write the title of the article in quotation marks, and include a period (or other closing punctuation) inside the closing quotation mark. The title of the magazine is next, underlined or in italic type, depending on whether you are handwriting or using a computer, followed by a period. The date and year, followed by a colon and the pages on which the article appeared, come last. Here is an example:

Format:  Author’s last name, first name. “Title of the Article.” Magazine. Month and year of publication: page numbers.

• Article in a monthly magazine : Crowley, J.E.,T.E. Levitan and R.P. Quinn.“Seven Deadly Half-Truths About Women.”  Psychology Today  March 1978: 94–106.
• Article in a weekly magazine : Schwartz, Felice N.“Management,Women, and the New Facts of Life.”  Newsweek  20 July 2006: 21–22.
• Signed newspaper article : Ferraro, Susan. “In-law and Order: Finding Relative Calm.”  The Daily News  30 June 1998: 73.
• Unsigned newspaper article : “Beanie Babies May Be a Rotten Nest Egg.”  Chicago Tribune  21 June 2004: 12.

Bibliography Entry for a Web Site

For sources such as Web sites include the information a reader needs to find the source or to know where and when you found it. Always begin with the last name of the author, broadcaster, person you interviewed, and so on. Here is an example of a bibliography for a Web site:

Format : Author.“Document Title.” Publication or Web site title. Date of publication. Date of access.

Example : Dodman, Dr. Nicholas. “Dog-Human Communication.”  Pet Place . 10 November 2006.  23 January 2014 < http://www.petplace.com/dogs/dog-human-communication-2/page1.aspx >

After completing the bibliography you can breathe a huge sigh of relief and pat yourself on the back. You probably plan to turn in your work in printed or handwritten form, but you also may be making an oral presentation. However you plan to present your paper, do your best to show it in its best light. You’ve put a great deal of work and thought into this assignment, so you want your paper to look and sound its best. You’ve completed your research paper!

How to Write a Bibliography (MLA, APA Examples)

Learn how to easily write a bibliography by following the format outlined in this article.

This resource will help your students properly cite different resources in the bibliography of a research paper, and how to format those citations, for books, encyclopedias, films, websites, and people.

What is a bibliography?

According to Infoplease.com, A bibliography is a list of the types of sources you used to get information for your report. It is included at the end of your report, on the last page (or last few pages).

What are the types of bibliography styles (MLA, APA, etc.)?

The 3 most common bibliography/citation styles are:

• MLA Style: The Modern Language Association works cited page style
• APA Style: The American Psychological Association style
• Chicago Style: The bibliography style defined by the Chicago Manual of Style

We’ll give examples of how to create bibliography entries in various styles further down in this article. 

What sources do you put in a bibliography?

An annotated bibliography should include a reference list of any sources you use in writing a research paper. Any printed sources from which you use a text citation, including books, websites, newspaper articles, journal articles, academic writing, online sources (such as PDFs), and magazines should be included in a reference list. In some cases, you may need or want to cite conversations or interviews, works of art, visual works such as movies, television shows, or documentaries - these (and many others) can also be included in a reference list.

How to get started writing your bibliography

You will find it easier to prepare your MLA, APA, or Chicago annotated bibliography if you keep track of each book, encyclopedia, journal article, webpage or online source you use as you are reading and taking notes. Start a preliminary, or draft, bibliography by listing on a separate sheet of paper all your sources. Note down the full title, author’s last name, place of publication, web address, publisher, and date of publication for each source.

How To Write a Bibliography (Three Styles, Plus Examples)

Give credit where credit is due.

Writing a research paper involves a lot of work. Students need to consult a variety of sources to gather reliable information and ensure their points are well supported. Research papers include a bibliography, which can be a little tricky for students. Learn how to write a bibliography in multiple styles and find basic examples below.

IMPORTANT: Each style guide has its own very specific rules, and they often conflict with one another. Additionally, each type of reference material has many possible formats, depending on a variety of factors. The overviews shown here are meant to guide students in writing basic bibliographies, but this information is by no means complete. Students should always refer directly to the preferred style guide to ensure they’re using the most up-to-date formats and styles.

What is a bibliography?

When you’re researching a paper, you’ll likely consult a wide variety of sources. You may quote some of these directly in your work, summarize some of the points they make, or simply use them to further the knowledge you need to write your paper. Since these ideas are not your own, it’s vital to give credit to the authors who originally wrote them. This list of sources, organized alphabetically, is called a bibliography.

A bibliography should include all the materials you consulted in your research, even if you don’t quote directly from them in your paper. These resources could include (but aren’t limited to):

• Books and e-books
• Periodicals like magazines or newspapers
• Online articles or websites
• Primary source documents like letters or official records

Bibliography vs. References

These two terms are sometimes used interchangeably, but they actually have different meanings. As noted above, a bibliography includes all the materials you used while researching your paper, whether or not you quote from them or refer to them directly in your writing.

A list of references only includes the materials you cite throughout your work. You might use direct quotes or summarize the information for the reader. Either way, you must ensure you give credit to the original author or document. This section can be titled “List of Works Cited” or simply “References.”

Your teacher may specify whether you should include a bibliography or a reference list. If they don’t, consider choosing a bibliography, to show all the works you used in researching your paper. This can help the reader see that your points are well supported, and allow them to do further reading on their own if they’re interested.

Bibliography vs. Citations

Citations refer to direct quotations from a text, woven into your own writing. There are a variety of ways to write citations, including footnotes and endnotes. These are generally shorter than the entries in a reference list or bibliography. Learn more about writing citations here.

What does a bibliography entry include?

Depending on the reference material, bibliography entries include a variety of information intended to help a reader locate the material if they want to refer to it themselves. These entries are listed in alphabetical order, and may include:

• Author/s or creator/s
• Publication date
• Volume and issue numbers
• Publisher and publication city
• Website URL

These entries don’t generally need to include specific page numbers or locations within the work (except for print magazine or journal articles). That type of information is usually only needed in a footnote or endnote citation.

What are the different bibliography styles?

In most cases, writers use one of three major style guides: APA (American Psychological Association), MLA (Modern Language Association), or The Chicago Manual of Style . There are many others as well, but these three are the most common choices for K–12 students.

Many teachers will state their preference for one style guide over another. If they don’t, you can choose your own preferred style. However, you should also use that guide for your entire paper, following their recommendations for punctuation, grammar, and more. This will ensure you are consistent throughout.

Below, you’ll learn how to write a simple bibliography using each of the three major style guides. We’ve included details for books and e-books, periodicals, and electronic sources like websites and videos. If the reference material type you need to include isn’t shown here, refer directly to the style guide you’re using.

APA Style Bibliography and Examples

Source: Verywell Mind

Technically, APA style calls for a list of references instead of a bibliography. If your teacher requires you to use the APA style guide , you can limit your reference list only to items you cite throughout your work.

How To Write a Bibliography (References) Using APA Style

Here are some general notes on writing an APA reference list:

• Title your bibliography section “References” and center the title on the top line of the page.
• Do not center your references; they should be left-aligned. For longer items, subsequent lines should use a hanging indent of 1/2 inch.
• Include all types of resources in the same list.
• Alphabetize your list by author or creator, last name first.
• Do not spell out the author/creator’s first or middle name; only use their initials.
• If there are multiple authors/creators, use an ampersand (&) before the final author/creator.
• Place the date in parentheses.
• Capitalize only the first word of the title and subtitle, unless the word would otherwise be capitalized (proper names, etc.).
• Italicize the titles of books, periodicals, or videos.
• For websites, include the full site information, including the http:// or https:// at the beginning.

Books and E-Books APA Bibliography Examples

For books, APA reference list entries use this format (only include the publisher’s website for e-books).

Last Name, First Initial. Middle Initial. (Publication date). Title with only first word capitalized . Publisher. Publisher’s website

• Wynn, S. (2020). City of London at war 1939–45 . Pen & Sword Military. https://www.pen-and-sword.co.uk/City-of-London-at-War-193945-Paperback/p/17299

Periodical APA Bibliography Examples

MLA style calls for a Works Cited section, which includes all materials quoted or referred to in your paper. You may also include a Works Consulted section, including other reference sources you reviewed but didn’t directly cite. Together, these constitute a bibliography. If your teacher requests an MLA Style Guide bibliography, ask if you should include Works Consulted as well as Works Cited.

How To Write a Bibliography (Works Cited and Works Consulted) in MLA Style

For both MLA Works Cited and Works Consulted sections, use these general guidelines:

• Start your Works Cited list on a new page. If you include a Works Consulted list, start that on its own new page after the Works Cited section.
• Center the title (Works Cited or Works Consulted) in the middle of the line at the top of the page.
• Align the start of each source to the left margin, and use a hanging indent (1/2 inch) for the following lines of each source.
• Alphabetize your sources using the first word of the citation, usually the author’s last name.
• Include the author’s full name as listed, last name first.
• Capitalize titles using the standard MLA format.
• Leave off the http:// or https:// at the beginning of a URL.

Books and E-Books MLA Bibliography Examples

For books, MLA reference list entries use this format. Add the URL at the end for e-books.

Published on 1 May 2020 by Jack Caulfield . Revised on 7 November 2022.

In Harvard style , the bibliography or reference list provides full references for the sources you used in your writing.

• A reference list consists of entries corresponding to your in-text citations .
• A bibliography sometimes also lists sources that you consulted for background research, but did not cite in your text.

The two terms are sometimes used interchangeably. If in doubt about which to include, check with your instructor or department.

The information you include in a reference varies depending on the type of source, but it usually includes the author, date, and title of the work, followed by details of where it was published. You can automatically generate accurate references using our free reference generator:

Reference list or bibliography entries always start with the author’s last name and initial, the publication date and the title of the source. The other information required varies depending on the source type. Formats and examples for the most common source types are given below.

• Book chapter

Sometimes a source won’t list all the information you need for your reference. Here’s what to do when you don’t know the publication date or author of a source.

Some online sources, as well as historical documents, may lack a clear publication date. In these cases, you can replace the date in the reference list entry with the words ‘no date’. With online sources, you still include an access date at the end:

When a source doesn’t list an author, you can often list a corporate source as an author instead, as with ‘Scribbr’ in the above example. When that’s not possible, begin the entry with the title instead of the author:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

In Harvard style referencing , to distinguish between two sources by the same author that were published in the same year, you add a different letter after the year for each source:

• (Smith, 2019a)
• (Smith, 2019b)

Add ‘a’ to the first one you cite, ‘b’ to the second, and so on. Do the same in your bibliography or reference list .

To create a hanging indent for your bibliography or reference list :

• Highlight all the entries
• Click on the arrow in the bottom-right corner of the ‘Paragraph’ tab in the top menu.
• In the pop-up window, under ‘Special’ in the ‘Indentation’ section, use the drop-down menu to select ‘Hanging’.
• Then close the window with ‘OK’.

Sample Bibliography

An APA format bibliography lists all of the sources that might be used in a paper. A bibliography can be a great tool to help you keep track of information during the research and writing process. In some cases, your instructor may require you to include a bibliography as part of your assignment.

At a Glance

A well-written APA format bibliography can help you keep track of information and sources as you research and write your psychology paper. To create a bibliography, gather up all of the sources that you might use in your paper. Create an APA format reference for each source and then write a brief annotation. Your annotation should be a brief summary of what each reference is about. You can quickly refer to these annotations When writing your paper and determine which to include.

What Is an APA Format Bibliography?

An APA format bibliography is an alphabetical listing of all sources that might be used to write an academic paper, essay, article, or research paper—particularly work that is covering psychology or psychology-related topics. APA format is the official style of the American Psychological Association (APA). This format is used by many psychology professors, students, and researchers.

Even if it is not a required part of your assignment, writing a bibliography can help you keep track of your sources and make it much easier to create your final reference page in proper APA format.

Creating an APA Bibliography

A bibliography is similar in many ways to a reference section , but there are some important differences. While a reference section includes every source that was actually used in your paper, a bibliography may include sources that you considered using but may have dismissed because they were irrelevant or outdated.

Bibliographies can be a great way to keep track of information you might want to use in your paper and to organize the information that you find in different sources. The following are four steps you can follow to create your APA format bibliography.

Start on a New Page

Your working bibliography should be kept separate from the rest of your paper. Start it on a new page, with the title "Bibliography" centered at the top and in bold text. Some people use the title "References" instead, so it's best to check with your professor or instructor about which they prefer you to use.

Gather Your Sources

Compile all the sources you might possibly use in your paper. While you might not use all of these sources in your paper, having a complete list will make it easier later on when you prepare your reference section.

Gathering your sources can be particularly helpful when outlining and writing your paper.

By quickly glancing through your working bibliography, you will be able to get a better idea of which sources will be the most appropriate to support your thesis and main points.

Reference Each Source

Your references should be listed alphabetically by the author’s last name, and they should be double-spaced. The first line of each reference should be flush left, while each additional line of a single reference should be a few spaces to the right of the left margin, which is known as a hanging indent.

The format of each source is as follows for academic journals:

• Last name of first author (followed by their first initial)
• The year the source was published in parentheses
• The title of the source
• The journal that published the source (in italics)
• The volume number, if applicable (in italics)
• The issue number, if applicable
• Page numbers (in parentheses)
• The URL or "doi" in lowercase letters followed by a colon and the doi number, if applicable

The following examples are scholarly articles in academic journals, cited in APA format:

• Kulacaoglu, F., & Kose, S. (2018). Borderline personality disorder (BPD): In the midst of vulnerability, chaos, and awe.  Brain sciences ,  8 (11), 201. doi:10.3390/brainsci8110201
• Cattane, N., Rossi, R., & Lanfredi, M. (2017). Borderline personality disorder and childhood trauma: exploring the affected biological systems and mechanisms.  BMC Psychiatry,   18 (221). doi:10.1186/s12888-017-1383-2

Visit the American Psychological Association's website for more information on citing other types of sources including online media, audiovisual media, and more.

Create an Annotation for Each Source

Normally a bibliography contains only references' information, but in some cases you might decide to create an annotated bibliography. An annotation is a summary or evaluation of the source.

An annotation is a brief description of approximately 150 words describing the information in the source, your evaluation of its credibility, and how it pertains to your topic. Writing one of these for each piece of research will make your writing process faster and easier.

This step helpful in determining which sources to ultimately use in your paper. Your instructor may also require it as part of the assignment so they can assess your thought process and understanding of your topic.

Reasons to Write a Bibliography

One of the biggest reasons to create an APA format bibliography is simply to make the research and writing process easier.

If you do not have a comprehensive list of all of your references, you might find yourself scrambling to figure out where you found certain bits of information that you included in your paper.

A bibliography is also an important tool that your readers can use to access your sources.

While writing an annotated bibliography might not be required for your assignment, it can be a very useful step. The process of writing an annotation helps you learn more about your topic, develop a deeper understanding of the subject, and become better at evaluating various sources of information.

The following is an example of an APA format bibliography by the website EasyBib:

There are many online resources that demonstrate different formats of bibliographies, including the American Psychological Association website . Purdue University's Online Writing Lab also has examples of formatting an APA format bibliography.

Check out this video on their YouTube channel which provides detailed instructions on formatting an APA style bibliography in Microsoft Word.

You can check out the Purdue site for more information on writing an annotated APA bibliography as well.

What This Means For You

If you are taking a psychology class, you may be asked to create a bibliography as part of the research paper writing process. Even if your instructor does not expressly require a bibliography, creating one can be a helpful way to help structure your research and make the writing process more manageable.

For psychology majors , it can be helpful to save any bibliographies you have written throughout your studies so that you can refer back to them later when studying for exams or writing papers for other psychology courses.

Creating an MLA Bibliography

If you write a research paper in MLA format, then you will need to include a Works Cited page according to the current 9th edition of the Modern Language Association (MLA) guidelines. Along with citing your sources within the body of your paper, you also need to include full citations of all sources at the end of your paper. The references in a bibliography are formatted in the same way as they would be in a Works Cited page. However, a bibliography refers to all works that you have consulted in your research, even if you did not use their information directly in your paper.

When you use the correct MLA bibliography format, it shows the reader what sources you consulted, makes finding your sources easier for the reader, and gives credibility to your work as a researcher and writer. This MLA sample paper will show you how the bibliography is incorporated into the rest of your paper. We also have a guide on APA reference pages , if you are following APA style in your paper.

Works cited or bibliography?

You may be wondering, what is a bibliography, and how is it different from a Works Cited page? The difference between the two is that while a bibliography refers to any source you consulted to write your research paper, a Works Cited page only includes full citations of the sources you quoted or paraphrased within your paper.

Typically, when someone says, “MLA bibliography” they really mean a Works Cited page, since the MLA format usually uses a Works Cited page instead of a bibliography.

A bibliography in MLA format may also refer to a Works Consulted page. If you used other sources that you did not directly quote or paraphrase within the paper, you will need to create a Works Consulted/Additional Resources page. A Works Consulted page starts on a separate page and follows the Works Cited page. It follows the same formatting guidelines as a Works Cited page, but you will use Works Consulted (or Additional Resources) as the title.

If you’re unsure of what to include in your citations list (works cited, works consulted, or both), ask your instructor. For the rest of this article, we will refer to this page as the MLA bibliography.

MLA bibliography formatting guidelines

These are the formatting rules you need to follow to create your bibliography according to MLA’s current edition guidelines. Your first page(s) will be your Works Cited page(s) and include the references that you directly refer to in your paper. Usually, this is all that is needed. If your instructor wants you to also include the works you consulted but did not include in your paper (more like a bibliography), then add Works Consulted or Additional Resources page for these sources.

• Your MLA Works Cited (and Works Consulted or Additional Resources pages) should begin on a separate page or pages at the end of your essay.
• Your essay should have a header on every page that includes your last name and the page number.
• The last name/page number header should be on the top right of each page with a ½ inch margin from the top of the page.
• One-inch margins.
• Title the page Works Cited (no italicization or quotation marks) unless otherwise instructed. Center the title. The top should look like this:

• Only center the Works Cited title; all citations should be left-justified.
• Double-space citations.
• Do not add an additional space between citations.
• After the first line, use a hanging indent of ½ inch on all additional lines of a citation. The hanging indent should look like this:

• Typically, this is the author’s last name, but sometimes it could be the title of the source if the author’s name is not available.

If you have a Works Consulted or Additional Resources page after your Works Cited page, format it in the same way, but with the title of Works Consulted or Additional Resources instead of Works Cited. Alternatively, your instructor may require a bibliography. If this is the case, all your sources, whether they are cited in your paper are not, are listed on the same page.

MLA citation guidelines

These are the rules you need to follow to create citations for an MLA bibliography. This section contains information on how to correctly use author names, punctuation, capitalization, fonts, page numbers, DOIs, and URLS in the citations on your MLA bibliography.

Author names

After the title Works Cited, the last name of the author of a source should be the first thing to appear on your page.

List the author’s last name followed by a comma, then the first name followed by the middle name or middle initial if applicable, without a comma separating the first and middle names. Add a period after the name.

Rowling, J.K.

Smith, Alexander McCall.

• Do not include titles such as Dr., Mrs., etc. or professional qualifications such as PhD, M.S., etc. with author names.
• Include suffixes such as Jr. or III after the author’s first name. Separate the first name and the suffix by a comma unless the suffix is a numeral. For example, to cite an author named John Smith, Jr., you would type Smith, John, Jr.

Sources with two authors

For a source with two authors, list the author names in your citation in the order they appear on the source, not alphabetically.

Type the last name of the first author listed on the source followed by a comma, then the first author’s first name followed by a comma. Then type the word “and” then list the second author’s first name and last name in the standard order. Follow the second name with a period.

Include middle names or initials and suffixes when applicable according to the guidelines for one author as listed above.

1st Author’s Last Name, First Name, and 2nd Author’s First Name Last Name.

Lutz, Lisa, and David Hayward.

Clark, Mary Higgins, and Alafair Burke.

Sources with three or more authors

For a source with three or more authors, only type the last and first name of the first author listed in the source, followed by a comma and the phrase et al., which is Latin for “and others.” Be sure to always place a period after the al in et al. but never after the et.

1st Author’s Last Name, First Name, et al.

Charaipotra, Sona, et al.

Williams, Beatriz, et al. All the Ways We Said Goodbye . HarperLuxe, 2020.

Organizations and corporations as authors

For sources with organizations or corporations listed as the author, type the name of the corporation in place of an author’s name. If the organization begins with an article like a, an, or the, it should be excluded in the Works Cited entry.

Modern Language Association of America. MLA Handbook . 2016.

*Note: If the organization is listed as both the author and the publisher, begin the citation with the title and include the organization’s name within the publisher field instead. 

For a source with no author listed, simply omit the author’s name and begin the citation with the title of the source. Use the first letter of the title when considering alphabetical order in your MLA bibliography.

Capitalization

Use MLA title case when citing titles of sources.

• Nouns, pronouns, verbs, adverbs, adjectives, and subordinating conjunctions should be capitalized.
• Articles, prepositions, and coordinating conjunctions should not be capitalized.

Font formatting

• Italicize the titles of larger works such as magazines and books. Also, italicize database and website names.
• Instead of italicization, use quotation marks around titles of shorter works such as poems, short stories, and articles.
• End all bibliography citations with a period.

Page numbers

Include page numbers in your full citations whenever possible. This helps the reader find the information you cited more quickly than if you just cited the entire source and lends more credibility to your argument. If you cite different pages from the same source within your paper, you should cite the entire source on your MLA bibliography instead of listing all of the page numbers you used.

When including page numbers in a citation, use the abbreviation p. to cite one page and the abbreviation pp. to cite multiple pages with a hyphen between the page numbers.

p. 25 or pp. 16-37

When citing page numbers in MLA, omit the first set of repeated digits.

pp. 365-69, not pp. 365-369

DOIs and URLs

A Digital Object Identifier (DOI) is used to locate and identify an online source. While URLs may change or web pages might be edited or updated, a DOI is permanent and therefore more useful in a source citation.

• Use a DOI (digital object identifier) whenever possible. Otherwise use a permalink or URL.
• DOIs should be formatted with “https://doi.org/” before the DOI number.
• Do not include “http://” or “https://” in your URLs.
• As either one will be the last part of your citation, place a period after the DOI or URL. (Note that this period is not part of the DOI or URL.)

Accessed dates

Since the previous 8th edition of the MLA Handbook was published, you do NOT need to list an accessed date for a stable source (e.g., online newspaper article, journal article, photograph, etc.). However, including an access date is good to include when a source does not have a publishing date, and some instructors will request that accessed dates be included for all sources.

If you do include an access date, here’s how to format it:

• Place it at the end of the citation without “http://” or “https://”.
• Write “Accessed” first, followed by the date accessed.
• The date accessed should be formatted as Day Month (abbreviated) Year.

Note: If you choose to list an accessed date after a DOI, the accessed date part of the citation will follow the period after the DOI and will end with a period at the end of the citation

MLA 8 th edition vs MLA 9 th edition

The 9 th edition of the MLA handbook re-introduces guidelines regarding paper formatting (which were not present in the 8 th edition). The guidance in the 9 th addition is consistent with the guidance in previous editions and expands on the formatting of tables, figures/illustrations, and lists. The 9 th edition also offers new guidance in areas like annotated bibliographies, inclusive language, and footnotes/endnotes.

Many of the differences between the 8 th edition and 9 th edition have to do with the formatting of the core elements in reference list entries. Some of the main changes include:

An MLA bibliography is similar to the Works Cited list that you include at the end of your paper. The only difference between a Works Cited list and a bibliography is that for the former, you need to include the entries for only the sources you cited in the text, whereas for the latter you can also include the sources you consulted to write your paper but didn’t directly cite in your writing. MLA generally prefers Works Cited lists to bibliographies.

If your instructor advises you to create an MLA bibliography, follow the same guidelines you would follow for creating an MLA Works Cited list.

The bibliography list appears at the end of the paper, after any endnotes if they are present.

All margins (top, bottom, left, and right) should be set at 1 inch.

Write the running head in the top right of the page at 0.5 inch from the top. Use the running head “Surname Page #.”

The font should be clear enough to read. Use Times New Roman font of size 12 points.

Entries should be double-spaced. If any entry runs over more than a line, indent the subsequent lines of the entry 0.5 inch from the left margin.

Bibliographic entries are arranged alphabetically according to the first item in each entry.

Title your bibliography as “Bibliography.”

General rules for creating an annotated bibliography

The annotation is given after the source entry and is generally about 100-150 words in length. The annotation should be indented 1 inch from the left margin to distinguish it from the hanging indent within the citation entry.

The annotation, in general, should be written as short phrases. However, you may use full sentences as well.

The annotation for each source is usually no longer than one paragraph. However, if multiple paragraphs are included, indent the second and subsequent paragraphs without any extra line space between them.

The annotation provides basic information about the source, but does not include details about the source, quotes from the author, etc. The information can be descriptive (by generally describing what the source covers) or evaluative (by evaluating the source’s usefulness to the argument in your paper).

Example annotated bibliography

The below is an example of an annotated bibliography:

Morritt, Robert D. Beringia: Archaic Migrations into North America . Cambridge Scholars Pub, 2011.

The author studies the migration of cultures from Asia to North America. The connection between the North American Athabaskan language family and Siberia is presented, together with comparisons and examinations of the implications of linguistics from anthropological, archaeological, and folklore perspectives. This book explores the origins of the earliest people in the Americas, including Siberian, Dene, and Navajo Creation myths; linguistic comparisons between Siberian Ket Navajo and Western Apache; and comparisons between indigenous groups that appear to share the same origin.

• If a journal article has a DOI, include the DOI in the reference.
• If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the  database information  page). The reference in this case is the same as for a print journal article.
• Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the  database information  page).
• If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.
• If the journal article has an article number instead of a page range, include the article number instead of the page range (as shown in the Jerrentrup et al. example).

• If the magazine article does not have a DOI and is from an academic research database, end the reference after the page range. Do not include  database information  in the reference. The reference in this case is the same as for a print magazine article.
• If the magazine article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online magazine that is not part of a database), include the URL of the article at the end of the reference.
• If the magazine article does not have volume, issue, and/or page numbers (e.g., because it is from an online magazine), omit the missing elements from the reference (as in the Schulman example).

Parenthetical citation:  (Carey, 2019)

• Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).

Parenthetical citation:  (Merriam-Webster, n.d.)

Narrative citation:  Merriam-Webster (n.d.)

• Because entries in  Merriam-Webster’s Dictionary  are updated over time and are not archived, include a  retrieval date  in the reference.
• Merriam-Webster is both the author and the publisher, so the name appears in the author element only to avoid repetition.
• To quote a dictionary definition, view the pages on quotations and  how to quote works without page numbers  for guidance. Additionally, here is an example:  Culture  refers to the “customary beliefs, social forms, and material traits of a racial, religious, or social group” (Merriam-Webster, n.d., Definition 1a).

Parenthetical citation:  (National Cancer Institute, 2019)

• Use the name of the account that uploaded the video as the author.
• If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere.

• Provide the first 20 words of the tweet as the title. Count a URL, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
• If the tweet includes an image, a video, a poll, or a thumbnail image with a link, indicate that in brackets after the title: [Image attached], [Video attached], [Thumbnail with link attached].
• The same format used for Twitter is also used for Instagram.  

Parenthetical citation:  (News From Science, 2019)

• When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
• When contents of a page are meant to be updated over time but are not archived, include a  retrieval date  in the reference (as in the Fagan example).
• Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the  newspaper article category  for articles from newspaper websites such as  The New York Times  or  The Washington Post .
• Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
• Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.

The following supplemental example references are mention in the  Publication Manual:

• retracted journal or magazine article
• edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
• edition of the International Statistical Classification of Diseases and Related Health Problems (ICD)
• religious work
• annotated religious work

Archival document and collections are not presented in the  APA Publication Manual, Seventh Edition . This content is available only on the APA Style website .  This guidance has been expanded from the 6th edition.

Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.

The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

Keep in mind the following principles when creating references to archival documents and collections:

• As with any reference, the purpose is to direct readers to the source, despite the fact that only a single copy of the document may be available and readers may have some difficulty actually seeing a copy.
• Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.
• If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations (see Example 3).
• Use square brackets to indicate information that does not appear on the document.
• Use “ca.” (circa) to indicate an estimated date (see Example 5).
• Use italics for titles of archival documents and collections; if the work does not have a title, provide a description in square brackets without italics.
• Separate elements of the source (e.g., the name of a repository, library, university or archive, and the location of the university or archive) with commas. End the source with a period.
• If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.
• Note that private letters (vs. those in an archive or repository) are considered personal communications and cited in the text only.

1. Letter from a repository

Frank, L. K. (1935, February 4). [Letter to Robert M. Ogden]. Rockefeller Archive Center (GEB Series 1.3, Box 371, Folder 3877), Tarrytown, NY, United States.

Read the full APA guidelines on citing ChatGPT 

OpenAI. (2023).  ChatGPT  (Mar 14 version) [Large language model].  https://chat.openai.com/chat

• Parenthetical citation:  (OpenAI, 2023)
• Narrative citation:  OpenAI (2023)

Author:  The author of the model is OpenAI.

Date:  The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title:  The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text  is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source:  When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is  https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

What to include and what to exclude

Works included in a reference list.

The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not  bibliographies.

In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.

Works Excluded From a Reference List

There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.

Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the  APA Publication Manual, Seventh Edition

*This guidance has been expanded from the 6th edition.*

• Personal communications  such as emails, phone calls, or text messages are cited in the text only, not in the reference list, because readers cannot retrieve personal communications.
• General mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar.
• The source of an epigraph does not usually appear in the reference list unless the work is a scholarly book or journal. For example, if you open the paper with an inspirational quotation by a famous person, the source of the quotation does not appear in the reference list because the quotation is meant to set the stage for the work, not substantiate a key point.   
• Quotations from research participants in a study you conducted can be presented and discussed in the text but do not need citations or reference list entries. Citations and reference list entries are not necessary because the quotations are part of your original research. They could also compromise participants’ confidentiality, which is an ethical violation.
• References included in a meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis.

DOIs and URLs

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A URL specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

Follow these guidelines for including DOIs and URLs in references:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If a print work does not have a DOI, do not include any DOI or URL in the reference.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most  academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. See the page on including  database information in references  for more information. 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, follow the guidance for works with  no source .
• Other alphanumeric identifiers such as the International Standard Book Number (ISBN) and the International Standard Serial Number (ISSN) are not included in APA Style references.

Follow these guidelines to format DOIs and URLs:

• Present both DOIs and URLs as hyperlinks (i.e., beginning with “http:” or “https:”).
• Because a hyperlink leads readers directly to the content, it is not necessary to include the words “Retrieved from” or “Accessed from” before a DOI or URL.
• It is acceptable to use either the default display settings for hyperlinks in your word-processing program (e.g., usually blue font, underlined) or plain text that is not underlined.
• Leave links live if the work is to be published or read online.
• Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of this publication is as follows:

https://doi.org/ xxxxx

• The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
• The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use  https://doi.org/10.1037/a0040251  in your reference even though that article, published in 2016, presented the number in an older format.
• Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
• Do not add a period after the DOI or URL because this may interfere with link functionality.

When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.

• Use the  shortDOI service  provided by the International DOI Foundation to create shortDOIs. A work can have only one DOI and only one shortDOI; the shortDOI service will either produce a new shortDOI for a work that has never had one or retrieve an existing shortDOI.
• Some websites provide their own branded shortened URLs, and independent URL shortening services are available as well. Any shortened URL is acceptable in a reference as long as you check the link to ensure that it takes you to the correct location.

APA Formatting and Citation (7th Ed.) | Generator, Template, Examples

Published on November 6, 2020 by Raimo Streefkerk . Revised on January 17, 2024.

The 7th edition of the APA Publication Manual provides guidelines for clear communication , citing sources , and formatting documents. This article focuses on paper formatting.

Generate accurate APA citations with Scribbr

Throughout your paper, you need to apply the following APA format guidelines:

• Set page margins to 1 inch on all sides.
• Double-space all text, including headings.
• Indent the first line of every paragraph 0.5 inches.
• Use an accessible font (e.g., Times New Roman 12pt., Arial 11pt., or Georgia 11pt.).
• Include a page number on every page.

Let an expert format your paper

Our APA formatting experts can help you to format your paper according to APA guidelines. They can help you with:

• Margins, line spacing, and indentation
• Font and headings
• Running head and page numbering

Are your APA in-text citations flawless?

The AI-powered APA Citation Checker points out every error, tells you exactly what’s wrong, and explains how to fix it. Say goodbye to losing marks on your assignment!

Get started!

References are ordered alphabetically by the first author’s last name. If the author is unknown, order the reference entry by the first meaningful word of the title (ignoring articles: “the”, “a”, or “an”).

Why set up APA format from scratch if you can download Scribbr’s template for free?

Student papers and professional papers have slightly different guidelines regarding the title page, abstract, and running head. Our template is available in Word and Google Docs format for both versions.

• Student paper: Word | Google Docs
• Professional paper: Word | Google Docs

In an APA Style paper, every page has a page header. For student papers, the page header usually consists of just a page number in the page’s top-right corner. For professional papers intended for publication, it also includes a running head .

A running head is simply the paper’s title in all capital letters. It is left-aligned and can be up to 50 characters in length. Longer titles are abbreviated .

Prevent plagiarism. Run a free check.

APA headings have five possible levels. Heading level 1 is used for main sections such as “ Methods ” or “ Results ”. Heading levels 2 to 5 are used for subheadings. Each heading level is formatted differently.

Want to know how many heading levels you should use, when to use which heading level, and how to set up heading styles in Word or Google Docs? Then check out our in-depth article on APA headings .

The title page is the first page of an APA Style paper. There are different guidelines for student and professional papers.

Both versions include the paper title and author’s name and affiliation. The student version includes the course number and name, instructor name, and due date of the assignment. The professional version includes an author note and running head .

For more information on writing a striking title, crediting multiple authors (with different affiliations), and writing the author note, check out our in-depth article on the APA title page .

The abstract is a 150–250 word summary of your paper. An abstract is usually required in professional papers, but it’s rare to include one in student papers (except for longer texts like theses and dissertations).

The abstract is placed on a separate page after the title page . At the top of the page, write the section label “Abstract” (bold and centered). The contents of the abstract appear directly under the label. Unlike regular paragraphs, the first line is not indented. Abstracts are usually written as a single paragraph without headings or blank lines.

Directly below the abstract, you may list three to five relevant keywords . On a new line, write the label “Keywords:” (italicized and indented), followed by the keywords in lowercase letters, separated by commas.

APA Style does not provide guidelines for formatting the table of contents . It’s also not a required paper element in either professional or student papers. If your instructor wants you to include a table of contents, it’s best to follow the general guidelines.

Place the table of contents on a separate page between the abstract and introduction. Write the section label “Contents” at the top (bold and centered), press “Enter” once, and list the important headings with corresponding page numbers.

The APA reference page is placed after the main body of your paper but before any appendices . Here you list all sources that you’ve cited in your paper (through APA in-text citations ). APA provides guidelines for formatting the references as well as the page itself.

Creating APA Style references

Play around with the Scribbr Citation Example Generator below to learn about the APA reference format of the most common source types or generate APA citations for free with Scribbr’s APA Citation Generator .

Formatting the reference page

Write the section label “References” at the top of a new page (bold and centered). Place the reference entries directly under the label in alphabetical order.

Finally, apply a hanging indent , meaning the first line of each reference is left-aligned, and all subsequent lines are indented 0.5 inches.

Tables and figures are presented in a similar format. They’re preceded by a number and title and followed by explanatory notes (if necessary).

Use bold styling for the word “Table” or “Figure” and the number, and place the title on a separate line directly below it (in italics and title case). Try to keep tables clean; don’t use any vertical lines, use as few horizontal lines as possible, and keep row and column labels concise.

Keep the design of figures as simple as possible. Include labels and a legend if needed, and only use color when necessary (not to make it look more appealing).

Check out our in-depth article about table and figure notes to learn when to use notes and how to format them.

The easiest way to set up APA format in Word is to download Scribbr’s free APA format template for student papers or professional papers.

Alternatively, you can watch Scribbr’s 5-minute step-by-step tutorial or check out our APA format guide with examples.

APA Style papers should be written in a font that is legible and widely accessible. For example:

• Times New Roman (12pt.)
• Arial (11pt.)
• Calibri (11pt.)
• Georgia (11pt.)

The same font and font size is used throughout the document, including the running head , page numbers, headings , and the reference page . Text in footnotes and figure images may be smaller and use single line spacing.

You need an APA in-text citation and reference entry . Each source type has its own format; for example, a webpage citation is different from a book citation .

Use Scribbr’s free APA Citation Generator to generate flawless citations in seconds or take a look at our APA citation examples .

Yes, page numbers are included on all pages, including the title page , table of contents , and reference page . Page numbers should be right-aligned in the page header.

To insert page numbers in Microsoft Word or Google Docs, click ‘Insert’ and then ‘Page number’.

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

Research Proposal and Annotated Bibliography

Most research essays involve two particular documents that help guide, manage, and report on the on-going research process. Those two documents are the research proposal and the annotated bibliography , detailed below.

Research Proposal

A research proposal is a brief document—only one typed page—that summarizes the preliminary ideas and current progress regarding your research essay. Your purpose is to formalize your plan for research and present it to your instructor for feedback. Your research proposal should be in complete sentences and paragraphs (and lists of information where appropriate), and should use MLA format.

A research proposal should address all of the following (the order of this information is allowed to change):

• Briefly summarize the subject and its issues, controversies, or context.
• Briefly explain of the significance or relevance of researching this subject.
• State your main research question about the subject.
• List any sub-questions related to your main research question (consider who, what, when, where, why, and how).
• State your working thesis.
• State the kinds of sources you plan to seek, or the types you have found, and/or your plan for finding sources.

Remember that your working thesis is not set in stone. You can and should change your working thesis throughout the research writing process if the information you find does not support your original thesis. Never try to force information into fitting your argument. For example, suppose your working thesis is this: “Mars cannot support life-forms.” Yet a week into researching your subject, suppose you find an article in the New York Times detailing new findings of bacteria under the Martian surface. Instead of trying to force that information into fitting your argument, such as arguing that bacteria are not life forms, you might instead alter your thesis to something like, “Mars cannot support complex life-forms.”

Below is an example of a research proposal from a student, which addresses all of the above:

Jorge Ramirez Prof. Habib Healthcare 101 March 25, 2015

In recent years, subjects related to diet, nutrition, and weight loss have been covered extensively in the mainstream media. Different experts recommend various, often conflicting strategies for maintaining a healthy weight. One highly recommended approach, which forms the basis of many popular diet plans, is to limit the consumption of carbohydrates. Yet experts disagree on the effectiveness and health benefits of this approach. What information should consumers consider when evaluating diet plans?

In my research, I will explore the claims made by proponents of the “low-carb lifestyle.” My primary research question is this: Are low-carbohydrate diets as effective for maintaining a healthy weight as they are portrayed to be?

My secondary research questions are these:

Who can benefit from following a low-carb diet?

What are the supposed advantages of following a low-carb diet?

When did low-carb diets become a hot topic in the media?

Where do average consumers get information about diet and nutrition?

Why has the low-carb approach received so much media attention?

How do low-carb diets work?

My working thesis is this: Low-carb diets are not as effective as the mass media attention suggests. In order to do this research, I will review mass media articles as well as scholarly articles that discuss the relationship between low-carb diets, weight loss, and long-term health. I will use general Google searches as well as Google Scholar, JSTOR, and other databases available through the campus library Website.

Write a research proposal. Make sure to address all of the following in complete sentences:

• brief summary of the subject and its issues or context
• brief explanation of the significance of researching this subject
• your main research question about the subject
• any sub-questions related to your main research question
• your working thesis
• the kinds of sources you plan to seek or have found, or your plan for finding sources

Annotated Bibliography

A bibliography is a list of all your sources and along with their citation information (in MLA format, the Works Cited page is a type of bibliography). An annotation is a note, description, and/or commentary on an item. So an annotated bibliography is a list of sources with notes, descriptions, and/or commentary on each source.

When engaging in a research writing project, creating and updating an annotated bibliography is extremely useful. It can function as your hub for collecting sources (so that you don’t lose or forget about them), as your reminder of what the source is about (so that you don’t have to re-read the whole piece), and as your aid in the writing process when selecting which sources are best to include where (so that you don’t have to memorize all of them while drafting and revising). An annotated bibliography can also help you avoid accidental plagiarism, which sometimes happens when students forget the sources of ideas or sentences they use in their essays.

Annotated bibliographies are thus a common assignment in courses that use research writing, even in alternate forms, such as the common high-school assignment of “note cards” (which are essentially annotated bibliographies on separate cards).

Whether or not you are assigned to create an annotated bibliography along with your research essay, you are wise to start one as soon as you read your first useful source. And you should keep adding to it and updating it as your research continues.

Take a look at an example entry for an annotated bibliography:

Pollan, Michael. “The New Science of Psychedelics.” The Wall Street Journal , May 3, 2018. Michael Pollan, https://michaelpollan.com/articles-archive/the-new-science-of-psychedelics .

This article is the author’s summary of his book How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression and Transcendence . It was first published in a reliable source, then republished on the author’s website. It is about the newly legal studies by major medical research institutions of the beneficial medical effects of psychedelics. Results for treating addiction and depression have been particularly positive. Pollan is a professional writer, not a medical professional. The primary subject in his career has been the modern food system. This article’s purpose is to reveal what’s new and possible with psychedelics, and to encourage further study. It is written in a calm, neutral, rational style, but one that stays vivid and interesting. It seems to be for an educated audience, but a broad one (not specialists).

Here are more details on the parts of an annotated bibliography and how to create them (along with the example pieces from the above entry):

I. Cite the source. Create the full Works Cited entry in MLA format that you would use as the citation in your essay. For online sources, including the full URL here can save a lot of time when returning to the source during drafting, revising, and editing.

II. Start a short paragraph below the citation for the annotation, and address the following:

1. Describe the source and its publication. Also mention its context, such as what it is a part of or is connected to, or how recent or relevant it is.

2. Summarize what the source is about. Include a brief mention of a detail or two that might be useful to your research project.

3. Discuss relevant information about the author, such as credentials, experience, reputation, or other publications.

4. Discuss the source’s purpose, bias, style, and/or intended audience.

5. Adjust the information you discuss in this paragraph as needed for the source, the research project, and/or the annotated bibliography assignment. For instance, you might wish to include a note to yourself about how you plan to use this source in your essay. Or the source might lack a stated author, which requires you to discuss the institution that produced the source instead. Also note that the above information does not have to remain in this order strictly.

To format your entire annotated bibliography with all of your entries, use standard MLA page layout. This means to include the standard first-page identifying information in the upper left (name, professor, course, date), a title (typically the words Annotated Bibliography), and alphabetical order for the entries. One common exception to this format is to use single-spaced entries, and leaving double-spacing between them. Find out from your instructor whether either is spacing style is preferred, or whether both are acceptable.

Create an annotated bibliography entry for an article as assigned by your instructor. Make sure to include all of the following:

Part I: Citation entry

Part II: Annotation paragraph

•  Describe the source and publication.
• Summarize the source.
• Discuss the author.
• Discuss the purpose, bias, style, and/or audience.
• Include any other relevant information.

Create an annotated bibliography for five sources that you might use for an upcoming research essay. Make sure use correct format and to include all of the following for each for the five entries:

• Describe the source and publication.

This handout provides information about annotated bibliographies in MLA, APA, and CMS.

Below you will find sample annotations from annotated bibliographies, each with a different research project. Remember that the annotations you include in your own bibliography should reflect your research project and/or the guidelines of your assignment.

As mentioned elsewhere in this resource, depending on the purpose of your bibliography, some annotations may summarize, some may assess or evaluate a source, and some may reflect on the source’s possible uses for the project at hand. Some annotations may address all three of these steps. Consider the purpose of your annotated bibliography and/or your instructor’s directions when deciding how much information to include in your annotations.

Please keep in mind that all your text, including the write-up beneath the citation, must be indented so that the author's last name is the only text that is flush left.

Sample MLA Annotation

Lamott, Anne. Bird by Bird: Some Instructions on Writing and Life . Anchor Books, 1995.

Lamott's book offers honest advice on the nature of a writing life, complete with its insecurities and failures. Taking a humorous approach to the realities of being a writer, the chapters in Lamott's book are wry and anecdotal and offer advice on everything from plot development to jealousy, from perfectionism to struggling with one's own internal critic.

In the process, Lamott includes writing exercises designed to be both productive and fun. Lamott offers sane advice for those struggling with the anxieties of writing, but her main project seems to be offering the reader a reality check regarding writing, publishing, and struggling with one's own imperfect humanity in the process. Rather than a practical handbook to producing and/or publishing, this text is indispensable because of its honest perspective, its down-to-earth humor, and its encouraging approach.

Chapters in this text could easily be included in the curriculum for a writing class. Several of the chapters in Part 1 address the writing process and would serve to generate discussion on students' own drafting and revising processes. Some of the writing exercises would also be appropriate for generating classroom writing exercises. Students should find Lamott's style both engaging and enjoyable.

In the sample annotation above, the writer includes three paragraphs: a summary, an evaluation of the text, and a reflection on its applicability to his/her own research, respectively.

Sample APA Annotation

Ehrenreich, B. (2001). Nickel and dimed: On (not) getting by in America . Henry Holt and Company.

In this book of nonfiction based on the journalist's experiential research, Ehrenreich attempts to ascertain whether it is currently possible for an individual to live on a minimum-wage in America. Taking jobs as a waitress, a maid in a cleaning service, and a Walmart sales employee, the author summarizes and reflects on her work, her relationships with fellow workers, and her financial struggles in each situation.

An experienced journalist, Ehrenreich is aware of the limitations of her experiment and the ethical implications of her experiential research tactics and reflects on these issues in the text. The author is forthcoming about her methods and supplements her experiences with scholarly research on her places of employment, the economy, and the rising cost of living in America. Ehrenreich’s project is timely, descriptive, and well-researched.

The annotation above both summarizes and assesses the book in the citation. The first paragraph provides a brief summary of the author's project in the book, covering the main points of the work. The second paragraph points out the project’s strengths and evaluates its methods and presentation. This particular annotation does not reflect on the source’s potential importance or usefulness for this person’s own research.

Sample Chicago Manual of Style Annotation

Davidson, Hilda Ellis. Roles of the Northern Goddess . London: Routledge, 1998.

Davidson's book provides a thorough examination of the major roles filled by the numerous pagan goddesses of Northern Europe in everyday life, including their roles in hunting, agriculture, domestic arts like weaving, the household, and death. The author discusses relevant archaeological evidence, patterns of symbol and ritual, and previous research. The book includes a number of black and white photographs of relevant artifacts.

This annotation includes only one paragraph, a summary of the book. It provides a concise description of the project and the book's project and its major features.

Title: can llms learn from previous mistakes investigating llms' errors to boost for reasoning.

Abstract: Recent works have shown the benefits to LLMs from fine-tuning golden-standard Chain-of-Thought (CoT) rationales or using them as correct examples in few-shot prompting. While humans can indeed imitate correct examples, learning from our mistakes is another vital aspect of human cognition. Hence, a question naturally arises: \textit{can LLMs learn and benefit from their mistakes, especially for their reasoning? } This study investigates this problem from both the prompting and model-tuning perspectives. We begin by introducing \textsc{CoTErrorSet}, a new benchmark with 609,432 questions, each designed with both correct and error references, and demonstrating the types and reasons for making such mistakes. To explore the effectiveness of those mistakes, we design two methods: (1) \textbf{Self-rethinking} prompting guides LLMs to rethink whether they have made similar previous mistakes; and (2) \textbf{Mistake tuning} involves finetuning models in both correct and incorrect reasoning domains, rather than only tuning models to learn ground truth in traditional methodology. We conduct a series of experiments to prove LLMs can obtain benefits from mistakes in both directions. Our two methods offer potentially cost-effective strategies by leveraging errors to enhance reasoning capabilities, which costs significantly less than creating meticulously hand-crafted golden references. We ultimately make a thorough analysis of the reasons behind LLMs' errors, which provides directions that future research needs to overcome. \textsc{CoTErrorSet} will be published soon on \texttt{Anonymity Link}.
