Primary vs. Secondary Sources: Primary vs. Secondary Sources
Primary sources.
Primary sources are materials that are eyewitness accounts or as close to the original source as possible.
Qualitative data:
- What people say. They are usually Speeches , Interviews and Conversations, and they may be captured in Videos, Audio Recordings, or transcribed into text.
- What people write. These include Autobiographies, Memoirs, Personal Journals and Diaries, Letters, Emails, Blogs, Twitter Feeds and other forms of Social Media.
- Images and Videos.
- Government Documents-- U.S . and rest of the world.
- Laws, Court Cases and Decisions, Treaties.
- Newspapers.
Quantitative data:
- Statistics and Data .
- Polls and Public Opinions .
Please note that a book is simply a format. You can find both primary and secondary sources published in book form.
Secondary Sources
Secondary sources are interpretations and analyses based on primary sources.
For example, an autobiography is a primary source while a biography is a secondary source.
Typical secondary sources include:
- Scholarly Journal Articles. Use these and books exclusively for writing Literature Reviews.
- Encyclopedias.
- Dictionaries.
- Documentaries.
Please note that a book is simply a format. You can find primary and secondary sources published in book form.
When Secondary Sources Become Primary Sources
Often secondary and primary sources are relative concepts. Typical secondary sources may be primary sources depending on the research topic.
- Intellectual history topics. For example, although scholarly journal articles are usually considered secondary sources, if one's topic is the history of human rights, then journal articles on human rights will be primary sources in this instance. Similarly, research on the thinking of a scholar will include her published journal articles as primary sources.
- Historical topics. Magazine articles are secondary sources, but for someone researching the view of judicial punishment in the 1920s, magazines from that time period are primary sources. Indeed, any older publication, such as those prior to the 20th century, is very often automatically considered a primary source.
- Newspapers may be either primary or secondary. Most articles in newspapers are secondary, but reporters may be considered as witnesses to an event. Any topic on the media coverage of an event or phenomenon would treat newspapers as a primary source. There are so many articles and types of articles in newspapers that newspapers can often be considered either primary or secondary.

Is a Biography a Primary Source? Details Every Author Should Know
POSTED ON Oct 1, 2023
Written by Shannon Clark
Is a biography a primary source? Good question.
When writing for an audience, adding relevant quotes, excerpts, and data provides credibility to your work. Primary sources reign supreme because information that comes from the original source leaves little room for error. In our digital age, where so much information is repeated from website to website, it's easy for data to be mistyped, quotes to be misattributed, and information to just be wrong.
It's similar to the group game, Telephone, that kids play. One person starts the game by whispering a phrase into the person's ear next to them. The phrase is repeated until it gets to the last person who says the phrase out loud to see if the message changed. When I played it as a little girl, the phrase hardly ever came out like the original. We run the same risk when we copy statistics or information from random websites that aren't the primary or original source.
In the first half of this article, we'll answer the question, “Is a biography a primary source?” define what the answer means, and then take a closer look at why biographies are categorized as such. In the second part, we’ll look at what to consider before writing one.
Table of Contents
Is a biography a primary source.
The short answer is no. In most cases, a biography is considered a secondary source; however, there’s a little more to it than that.
A primary source is a first-person account (e.g., direct quote, diary entry) or the original source of information (e.g., a research organization that creates original data for an industry.).
A secondary source is a third-party account where the person or company sharing the information, got it from somewhere else. As I mentioned in the Telephone example, the problem with secondary sources is that since they aren't the first hands to touch the information, there's no guarantee that it's correct. Primary sources aren't always available, but if you have a choice between the two, do the extra research to find the primary source. It will pay off in the long run.
A biography is a third-person account of another person’s life written by a biographer whose name appears on the cover. The subject of the biography can be living or deceased and the work can be authorized or unauthorized. For these reasons, biographies are classified as secondary sources.
Related: Biography vs Memoir
The rare occasion when a biography can be used as a primary source is when the biographer is the subject of the content being written.
For example, if one were to write an article that analyzed the works of the American biographer Jean Strouse, her best biographies , Alice James: A Biography or Morgan: American Financier would be considered primary sources.
The source status of her biographies changes from secondary to primary because it is her writing that's being analyzed not the personal knowledge of what she wrote (unless that was part of the review).
What’s the Difference Between an Authorized and an Unauthorized Biography?
With an authorized biography, the subject of the work is either involved in the writing process or they’ve given permission for the biographer to write the book. The biographer works with the person to ensure that the information included is correct and approved. This can include talking to close family members and friends to get a more well-rounded, objective view of the person's life.
Unauthorized biographies are not approved by the subject. Anyone can write an unauthorized biography about anyone they’d like. You don’t need permission, and the final book doesn’t have to be approved to be published; however, unauthorized biographies can be seen as less reliable than approved ones. Content presented as fact may come into question exposing the work to libel, invasion of privacy claims, and other legal issues. To be clear, biographies, autobiographies, and memoirs can all be vulnerable to legal claims, so tread lightly when writing them.
According to the Writer’s GPS: A guide for navigating the legal landscape of publishing by intellectual property attorney Matt Knight, securing life story rights is key to protecting yourself and your book from legal claims. Regarding life story rights, he says the following:
Life story rights are a collection of legal rights held by an individual regarding a story about someone's life. The purpose for securing these rights or the permission to use the facts of someone's life is to protect the writer and publisher from being sued for defamation, invasion of privacy, or the misappropriation of the right to publicity. Life story rights agreements, depending on the breadth of the contract language, allows the writer to use and potentially change or dramatize the life story for entertainment purposes (whether in print or on screen). Knight, M. (2020). The Writer’s Legal GPS: A Guide for Navigating the Legal Landscape of Publishing (A Sidebar Saturdays Desktop Reference) . Sidebar Saturdays Desk Referen.
If you're considering writing a biography (authorized or unauthorized), it's important to understand potential liability issues and how they can impact you as the writer.
It's interesting that for every authorized biography, it is not uncommon to find many unauthorized ones. For actress Elizabeth Taylor, the book on the left (below) was released in December 2022 and listed as “ the first ever authorized biography of the most famous movie star of the twentieth century, Elizabeth Taylor “; however, I found many biographies listed for her over the years (I stopped counting at 20).
Is it Possible to Write a Biography about Yourself?
No. If you write a biography about yourself it is called an autobiography (different from a memoir). If you get a ghostwriter to write it, it is still an autobiography. Autobiographies are primary sources because they are first-hand accounts based on the subjects' memories and recall of past experiences.
Unlike a biography, the subject of the autobiography is viewed as the author , whether they wrote it or used a ghostwriter . Autobiographies are considered subjective compared to biographies since they are a single person's account of events (not friends, family, or other third-party references like with a biography.)
How do You Write a Biography About Someone Who Has Passed?
As previously mentioned, if you can get permission to write the biography, do so. If the person is deceased, look for a representative, like a family member, or an executor of their estate. It’s important to share with them your plan for writing the person’s life story and hopefully get the green light to move forward. Getting approval can open the door to accessing archives and other personal details about the person to create a more in-depth work. This can include personal photos, diaries, and other information. Compare this to an unauthorized biography where you may only have access to what has already been talked about or uncovered.
If the person passed a long time ago, getting permission might be a challenge, but you can still write the biography. Just do your research, save your notes, and try to write a biography that is thorough, objective, and professional. Prioritize primary sources over secondary and cite all of your sources to add credibility. It may be tempting to try to rush through the process, especially when you've been staring at the same information day after day, but doing a thorough job can pay big dividends.
In the writing of the Pulitzer Prize-winning biography American Prometheus: The Triumph and Trajedy of J. Robert Oppenheimer , it took author, Martin J. Sherwin, 25 years to complete the work. The first 20 years were spent doing interviews and collecting over fifty boxes of archives (some received through the Freedom of Information Act). The last five years he partnered with author Kai Bird to complete the work . While it doesn't take every biographer that long to write a biography, it does add a weighty perspective to what writing an in-depth book about someone's life could entail.
Whether you write an authorized or unauthorized biography, the quality and objectivity of your writing are what matter most. Although biographies are considered secondary sources, it doesn’t mean that they can’t make a significant contribution to the tapestry of a person’s public life record.
Seek out the permission of the person you want to write about if they are living or their family or representative if they are incapacitated or deceased. People’s life stories are personal, so the best advice from one writer to another is to write their stories with the same respect you’d want someone to write yours. This will add a strong entry to your book portfolio, save you a lot of headaches in the long run, and help keep you out of a courtroom.
Note: In this article, we touched on nonfiction life stories, but there are also biographical novels (fictitious) and autobiographical fiction that are not within the scope of this article. For more information on creative nonfiction, start here .

Definitions (from Pennington School)
A primary source is an original material created during the time under study. Primary sources can be original documents, creative works, published materials of the times, institutional and government documents or relics and artifacts
Secondary sources put primary sources in context. They comment, summarize, interpret or analyze information found in primary sources. Secondary sources are usually written by individuals who did not experience firsthand the events about which they are writing.
Examples (from Penington School)
Selected sources.
- Primary, Secondary or Tertiary Sources Tertiary sources: good for an overview; can help narrow a topic Secondary sources: sources created after the time of the event and not contemporaneous with the lifetime of the person Primary sources: original objects or documents created near the time being studied.

Primary vs. Secondary Sources: A Questionnaire
Answer the questions below about your source. If you answer, “yes” to any of the following questions, there is a good chance the source is PRIMARY.
Did the author personally witness or experience the subject in question? Does the author know about this subject because of personal experience rather than having just read about it? Is this source a diary, letter, memoir, autobiography, oral history, or interview of a person with first hand experience of the subject? Is this source an official document or record published at the time of the event by the government, courts, or another organization? Is this source a newspaper or magazine article written at the time of the event? Is this a creative work such as a novel, poem, art or music piece created by a firsthand witness of the subject in question? Is this an excerpt from a primary source, such as the constitution or a letter written by a Civil War soldier that has been imbedded in a secondary source, such as a textbook?Remember, secondary sources may include reprints of primary sources. Is this an artifact or relic such as jewelry, pottery, clothing, music, art, architecture, dance or weaponry that was used by witnesses of the subject in question? Is this a compilation of raw scientific data or statistics, such as census statistics published by the U.S. Census Bureau, that is being published without commentary or interpretation?

Primary vs. Secondary Sources | Difference & Examples
Published on 4 September 2022 by Raimo Streefkerk . Revised on 15 May 2023.
When you do research, you have to gather information and evidence from a variety of sources.
Primary sources provide raw information and first-hand evidence. Examples include interview transcripts, statistical data, and works of art. A primary source gives you direct access to the subject of your research.
Secondary sources provide second-hand information and commentary from other researchers. Examples include journal articles, reviews, and academic books . A secondary source describes, interprets, or synthesises primary sources.
Primary sources are more credible as evidence, but good research uses both primary and secondary sources.

What is a primary source, what is a secondary source, primary and secondary source examples, how to tell if a source is primary or secondary, primary vs secondary sources: which is better, frequently asked questions about primary and secondary sources.
A primary source is anything that gives you direct evidence about the people, events, or phenomena that you are researching. Primary sources will usually be the main objects of your analysis.
If you are researching the past, you cannot directly access it yourself, so you need primary sources that were produced at the time by participants or witnesses (e.g. letters, photographs, newspapers ).
If you are researching something current, your primary sources can either be qualitative or quantitative data that you collect yourself (e.g. through interviews, surveys, experiments) or sources produced by people directly involved in the topic (e.g. official documents or media texts).

A secondary source is anything that describes, interprets, evaluates, or analyses information from primary sources. Common examples include:
- Books , articles and documentaries that synthesise information on a topic
- Synopses and descriptions of artistic works
- Encyclopaedias and textbooks that summarize information and ideas
- Reviews and essays that evaluate or interpret something
When you cite a secondary source, it’s usually not to analyse it directly. Instead, you’ll probably test its arguments against new evidence or use its ideas to help formulate your own.
Examples of sources that can be primary or secondary
A secondary source can become a primary source depending on your research question . If the person, context, or technique that produced the source is the main focus of your research, it becomes a primary source.
To determine if something can be used as a primary or secondary source in your research, there are some simple questions you can ask yourself:
- Does this source come from someone directly involved in the events I’m studying (primary) or from another researcher (secondary)?
- Am I interested in analysing the source itself (primary) or only using it for background information (secondary)?
- Does the source provide original information (primary) or does it comment upon information from other sources (secondary)?
Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research.
What do you use primary sources for?
Primary sources are the foundation of original research. They allow you to:
- Make new discoveries
- Provide credible evidence for your arguments
- Give authoritative information about your topic
If you don’t use any primary sources, your research may be considered unoriginal or unreliable.
What do you use secondary sources for?
Secondary sources are good for gaining a full overview of your topic and understanding how other researchers have approached it. They often synthesise a large number of primary sources that would be difficult and time-consuming to gather by yourself. They allow you to:
- Gain background information on the topic
- Support or contrast your arguments with other researchers’ ideas
- Gather information from primary sources that you can’t access directly (e.g. private letters or physical documents located elsewhere)
When you conduct a literature review , you can consult secondary sources to gain a thorough overview of your topic. If you want to mention a paper or study that you find cited in a secondary source, seek out the original source and cite it directly.
Remember that all primary and secondary sources must be cited to avoid plagiarism . You can use Scribbr’s free citation generator to do so!
Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.
Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.
Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.
Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.
To determine if a source is primary or secondary, ask yourself:
- Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
- Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
- Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?
Some types of sources are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.
Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.
Always make sure to properly cite your sources to avoid plagiarism .
A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.
If you are directly analysing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.
If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.
Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .
Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.
In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyse language and social relations (for example, by conducting content analysis or discourse analysis ).
If you are not analysing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

A primary source is an original document containing firsthand information about a topic.
Different fields of study may use different types of primary sources. Common examples of a primary source are:
- Autobiographies
- Eyewitness Accounts
- Interview Transcripts
- Legal Documents
- Original works of art
- Photographs of the topic
- Original Research
- Video Footage of the topic event
- Works of literature
Secondary Sources
A secondary source contains commentary on or discussion about a primary source. The most important feature of secondary sources is that they offer an interpretation of information gathered from primary sources.
Common examples of a secondary source are:
- Biographies
- Indexes, Abstracts, Bibliographies (used to locate a secondary source)
- Journal Articles
- Literary Criticism
- Monographs written about the topic
- Reviews of books, movies, musical recordings,. works of art, etc.
Primary vs. Secondary Information
Primary sources are first hand sources; secondary sources are second-hand sources. For example, suppose there had been a car accident. The description of the accident which a witness gives to the police is a primary source because it comes from someone who was actually there at the time. The next day's newspaper story is a secondary source because the reporter who wrote the story did not actually witness the event. The reporter is presenting a way of understanding the accident or an interpretation.
*From North Park University, History Department
However , the distinctions between primary and secondary sources can be ambiguous. It is important to remember that you cannot determine whether a source is primary or secondary solely based on the document type. An individual document may be a primary source in one context and a secondary source in another. For example, the movie Love, Marilyn is a secondary source when the topic is Marilyn Monroe; it would be considered a primary source if the topic of research was the works of Liz Garbus (the film's director).
Additionally, time can be a defining element. For example, a recent newspaper article is not usually a primary source; but a newspaper article from the 1860s may be a primary source for United States Civil War research.
*From CBB Library and IT Consortium
Examples of Primary and Secondary Sources
Sometimes, the same source might be a primary source for one research paper and a secondary source for another. It all depends on the relationship of the source to your research question. For example, if you are researching Franklin Roosevelt's life, the book No ordinary time: Franklin and Eleanor Roosevelt: The home front in World War II by Doris Kearns Goodwin would be a secondary source. If you were researching the literary style of Ms. Goodwin, it would be a primary source.

Primary sources provide the raw data you use to support your arguments. Some common types of primary resources include manuscripts, diaries, court cases, maps, data sets, experiment results, news stories, polls, or original research. In many cases what makes a primary resource is contextual. For example, a biography about Abraham Lincoln is a secondary resource about Lincoln. However, if examined as a piece of evidence about the nature of biographical writing, or as an example of the biographer's writing method it becomes a primary resource.

Primary, Secondary, & Tertiary Sources

- Examples by Discipline
What are secondary sources?
Secondary sources depend upon primary sources. Secondary sources describe, discuss, interpret, comment upon, analyze, evaluate, summarize, and process primary sources. The important thing to keep in mind when trying to decide if a source is primary or secondary is whether or not the author did the thing they are reporting on. If they did, it is a primary source; if they did not, it is a secondary source.
What is the role of secondary sources in research?
Secondary sources represent the scholarly conversation that has taken place, or is currently taking place, on a given topic. Thus, it is imperative that researchers acquire a comprehensive knowledge of the secondary literature on their topic to be able to then engage with it and offer their own perspective through their writing. Scholars show their deep knowledge of their topic by demonstrating in their writing their awareness of secondary literature. Research that does not include substantial references to both primary and secondary sources is not likely to be authoritative or reliable. For that reason, looking at the listed references in a piece of research can help you determine its value.
What are some examples of secondary sources?
Like primary sources, secondary sources can be lots of different kinds of resources depending on discipline and application. Secondary sources can be:
- Journal articles
- Monographs (books written on a single subject)
- Newspaper or magazine articles
- Book or movie reviews
In the sciences, secondary sources tend to be things like literature reviews (synthesized descriptions of previous scholarship on a topic), systematic reviews (overviews of primary sources on a topic), or meta analyses (studies in which conclusions are drawn from consideration of systematic reviews).
In the humanities, secondary sources tend to be journal articles that discuss or evaluate someone else's research, monographs, or reviews.

What is a Secondary Source?
Secondary sources are books, periodicals, web sites, etc. that people write using the information from primary sources. They are not written by eyewitnesses to events, for instance, but use eyewitness accounts, photographs, diaries and other primary sources to reconstruct events or to support a writer's thesis about the events and their meaning. Many books you find in the Cornell Library Catalog are secondary sources.

What Is a Secondary Source?
Secondary sources are written by someone who was not present during the event or condition under discussion. Authors of secondary sources use primary sources or other secondary sources to gather their information.
When doing historical research, it is important to distinguish between primary and secondary sources.
" Primary sources provide first-hand testimony or direct evidence concerning a topic under investigation. They are created by witnesses or recorders who experienced the events or conditions being documented. Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later. Primary sources are characterized by their content, regardless of whether they are available in original format, in microfilm/microfiche, in digital format, or in published format."

Other Indexes
History of Science, Technology and Medicine [HSTM], 1975- .
Includes books, book chapters, and journal articles. Includes medicine and social science as well as science and technology. Electronic equivalent of four printed indexes:
- Isis Current Bibliography of the History of Science and its Cultural Influences , 1975-. [Coverage of book reviews begins (in a small way) in 2000 and becomes substantial in 2002. Enter the phrase "book review" in the title field along with the title of the book. Use print version for earlier book reviews (see below)]
- Current Bibliography in the History of Technology , 1987- . [Book reviews included]
- Wellcome Bibliography of the History of Medicine , 1991-2004. [No book reviews]
- Bibliografia italiana di storia della scienza , 1982- . [Book reviews included]
Since HSTM is an amalgamation of four separate indexes with four different subject term systems, study the results of keyword searches to be sure that you know the proper subject terms for your topic in each of the, possibly four, relevant component databases. For example, the Wellcome Bibliography uses "Contraception" but the Isis Current Bibliography uses "Birth control".
Limiting by Time Period
Note the different terms used by these three indexes: Isis Current Bibliography of the History of Science and its Cultural Influences : Pre-history, Antiquity, Middle Ages, Renaissance (15th and 16th), 17th century, 18th century, 19th century, 20th century Current Bibliography in the History of Technology: Prehistory, Antiquity, Middle Ages, Renaissance, 17th century, 18th century, 19th century, 20th century Wellcome Bibliography of the History of Medicine : Ancient, Greek and Roman, Medieval, 13th century , 14th century , 15th century , 16th century, 17th century, 18th century, 19th century, 20th century
Searching for literature published before 1975 (pre-HSTM)

What is a secondary source?
A Secondary source is a work written about an event or person after it has taken place. Some examples:
- Academic Article
- Most websites
- Media depictions (ex. films)
- Documentaries
- Reinactments
Types of Secondary Sources
In Academe, we are especially interested in a specific type of secondary source: Peer Reviewed Publications.
But what's the difference between scholarly, peer reviewed, popular, or refereed? Scholarly : A source written by an expert, but not subjected to the peer review process. Example: magazine articles (if written by expert), public presentations, reviews, opinion pieces. Refereed : Academic work that has some level of vetting, usually by an editor or panel. Example: Conference papers, journal articles that are approved by an editor but not external reviewers. NOTE: refereed is often used interchangeably with Peer Reviewed by databases, but it isn't always the same. Popular : Written for a wide readership. May or may not be written by a subject expert. Examples: newspaper or magazine, popular press books, websites. Peer Reviewed : Academic books and articles written by a specialist, reviewed by other experts, and published by an academic press. Examples: Articles in academic journals, some conference papers, books published by university presses.

Primary vs. Secondary Sources
- Scholarly Sources
- Finding Secondary (and Scholarly) Sources
A secondary source is one that was created later by someone that did not experience firsthand or participate in the events in which the author is writing about. Secondary sources often summarize, interpret, analyze or comment on information found in primary sources.
Common examples of secondary sources include:
- Biographies
- Literary Criticism
- Journal articles that do not present new research

Biographies
Use a biography when you are looking for facts and accounts about notable people. An autobiography is a biography in which the author writes about his or her own life. Many biographies focus on one person.Some are collective biographies which have information about multiple people. Some collective biographies are subject specific, like a book or series about famous scientists or one about actors.
When do I use a biography? Use a biography when you need the following:
- quick facts about an individual
- in-depth information about an individual
- information about an individual's role in a specific event (e.g., Abraham Lincoln and Emancipation Proclamation)
Where do I find a biography? Look for a biography in the reference or nonfiction sections of your library. Often the books have a call number of 921, 920 (collective), B or Bio, or the number associated with what the individual is noted for (e. g., athletes in 796 or mathematicians in 510). Use your library's online catalog to find the call number by using the person's name in a subject search. Or, enter the topic you are interested in, like athletes or mathematician s, and adding biography as a keyword.
How is a biography organized? Biographies can be arranged in a variety of ways. Some cover a person's entire life, and others focus on a significant contribution or event. In the case of collective biographies, a chapter or section will often focus on one individual.
How do I use a print biography? Think about what information you need. Use the table of contents to see how the book is arranged, and use the index to locate the specific pieces of information you need. In a collective biography, the index will list names of individuals and also related topics and events.
The index will be in alphabetical order by main headings (usually in bold print) and subheadings (usually indented):
How do I use an online biography? Your public or school library might have eBook biographies about the person you are studying. Check the online catalogs or databases. Also, there are websites dedicated to biographical information, like Biography.com and History.com. Browse by topics or use the website's, eBook's, or database's search features. Or, use a search engine to search the Internet for information about your subject.

Welcome to the Purdue OWL
This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.
Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.
Basic Format for Books
Edited book, no author, edited book with an author or authors, a translation.
Note : When you cite a republished work, like the one above, in your text, it should appear with both dates: Plato (385-378/1989)
Edition Other Than the First
Article or chapter in an edited book.
Note : When you list the pages of the chapter or essay in parentheses after the book title, use "pp." before the numbers: (pp. 1-21). This abbreviation, however, does not appear before the page numbers in periodical references, except for newspapers. List any edition number in the same set of parentheses as the page numbers, separated by a comma: (2nd ed., pp. 66-72).
Multivolume Work
Articles in periodicals.
APA style dictates that authors are named with their last name followed by their initials; publication year goes between parentheses, followed by a period. The title of the article is in sentence-case, meaning only the first word and proper nouns in the title are capitalized. The periodical title is run in title case, and is followed by the volume number which, with the title, is also italicized. If a DOI has been assigned to the article that you are using, you should include this after the page numbers for the article. If no DOI has been assigned and you are accessing the periodical online, use the URL of the website from which you are retrieving the periodical.
Article in Print Journal
Note: APA 7 advises writers to include a DOI (if available), even when using the print source. The example above assumes no DOI is available.
Article in Electronic Journal
Note : This content also appears on Reference List: Online Media .
As noted above, when citing an article in an electronic journal, include a DOI if one is associated with the article.
DOIs may not always be available. In these cases, use a URL. Many academic journals provide stable URLs that function similarly to DOIs. These are preferable to ordinary URLs copied and pasted from the browser's address bar.
Article in a Magazine
Article in a newspaper.
