Parenthetical citations: (Grady et al., 2019; Jerrentrup et al., 2018)

Narrative citations: Grady et al. (2019) and Jerrentrup et al. (2018)

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).

Parenthetical citations: (Rabinowitz, 2019; Sapolsky, 2017)

Narrative citations: Rabinowitz (2019) and Sapolsky (2017)

If the book includes a DOI, include the DOI in the reference after the publisher name.
Do not include the publisher location.
If the book does not have a DOI and comes from an academic research database, end the book reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print book.

Parenthetical citations: (Schaefer & Shapiro, 2019; Schulman, 2019)

Narrative citations: Schaefer and Shapiro (2019) and Schulman (2019)

If a magazine article has a DOI, include the DOI in the reference.
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)

Narrative citation: Carey (2019)

If the newspaper article 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 newspaper article.
If the newspaper article has a URL that will resolve for readers (e.g., it is from an online newspaper), include the URL of the article at the end of the reference.
If the newspaper article does not have volume, issue, and/or page numbers (e.g., because it is from an online newspaper), omit the missing elements from the reference, as shown in the example.
If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a webpage on a website instead.

Parenthetical citation: (Aron et al., 2019)

Narrative citation: Aron et al. (2019)

If the edited book chapter includes a DOI, include the chapter DOI in the reference after the publisher name.
If the edited book chapter does not have a DOI and comes from an academic research database, end the edited book chapter reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print edited book chapter.
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)

Narrative citation: National Cancer Institute (2019)

The specific agency responsible for the report appears as the author. The names of parent agencies not present in the group author name appear in the source element as the publisher. This creates concise in-text citations and complete reference list entries.

Parenthetical citation: (Harvard University, 2019)

Narrative citation: Harvard University (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.

Parenthetical citations: (APA Databases, 2019; Gates, 2019)

Narrative citations: APA Databases (2019) and Gates (2019)

Present the name of the individual or group author the same as you would for any other reference. Then provide the Twitter handle (beginning with the @ sign) in square brackets, followed by a period.
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)

Narrative citation: News From Science (2019)

Provide the first 20 words of the Facebook post as the title. Count a URL or other link, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
If a status update includes images, videos, thumbnail links to outside sources, or content from another Facebook post (such as when sharing a link), indicate that in square brackets.

Parenthetical citations: (Fagan, 2019; National Institute of Mental Health, 2018; Woodyatt, 2019; World Health Organization, 2018)

Narrative citations: Fagan (2019), National Institute of Mental Health (2018), Woodyatt (2019), and World Health Organization (2018)

Provide as specific a date as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
Italicize the title of a webpage.
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.

Parenthetical citation: (Frank, 1935)
Narrative citation: Frank (1935)
Because the letter does not have a title, provide a description in square brackets.

2. Letter from a private collection

Zacharius, G. P. (1953, August 15). [Letter to William Rickel (W. Rickel, Trans.)]. Copy in possession of Hendrika Vande Kemp.

Parenthetical citation: (Zacharius, 1953)
Narrative citation: Zacharius (1953)
In this example, Hendrika Vande Kemp is either the author of the paper or the author of the paper has received permission from Hendrika Vande Kemp to cite a letter in Vande Kemp’s private collection in this way. Otherwise, cite a private letter as a personal communication .

3. Collection of letters from an archive

Allport, G. W. (1930–1967). Correspondence. Gordon W. Allport Papers (HUG 4118.10), Harvard University Archives, Cambridge, MA, United States.

Parenthetical citation: (Allport, 1930–1967)
Narrative citation: Allport (1930–1967)

To cite specific letters in the text, provide the author and range of years as shown in the reference list entry, plus details about who wrote the specific letter to whom and when the specific letter was written.

Parenthetical citation: (Allport, 1930–1967, G. Boring to Allport, December 26, 1937)
Narrative citation: Allport (1930–1967, Allport to G. Boring, March 1, 1939)
Use the parenthetical citation format to cite a letter that E. G. Boring wrote to Allport because Allport is the author in the reference. Use either the parenthetical or narrative citation format to cite letters that Allport wrote.

4. Unpublished papers, lectures from an archive or personal collection

Berliner, A. (1959). Notes for a lecture on reminiscences of Wundt and Leipzig. Anna Berliner Memoirs (Box M50), Archives of the History of American Psychology, University of Akron, Akron, OH, United States.

Parenthetical citation: (Allport, ca. 1937)
Narrative citation: Allport (ca. 1937)
Because the author is reasonably certain but not stated on the document, place the word “presumed” in parentheses after the name, followed by a period.
Because the date is reasonably certain but not stated on the document, the abbreviation “ca.” (which stands for “circa”) appears before the year in parentheses.

6. Archival source with group author

Subcommittee on Mental Hygiene Personnel in School Programs. (1949, November 5–6). Meeting of Subcommittee on Mental Hygiene Personnel in School Programs. David Shakow Papers (M1360), Archives of the History of American Psychology, University of Akron, Akron, OH, United States.

Narrative citation: Sci-Art Publishers (1935)

11. Archived photographs, no author and no title

[Photographs of Robert M. Yerkes]. (ca. 1917–1954). Robert Mearns Yerkes Papers (Box 137, Folder 2292), Manuscripts and Archives, Yale University Library, New Haven, CT, United States.

Parenthetical citation: ([Photographs of Robert M. Yerkes], ca. 1917–1954)
Narrative citation: [Photographs of Robert M. Yerkes] (ca. 1917–1954)
Because the archived photographs do not have a title, provide a bracketed description instead.

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.

What is APA Style?

APA style was created by social and behavioral scientists to standardize scientific writing. APA style is most often used in:

psychology,
social sciences (sociology, business), and

If you're taking courses in any of these areas, be prepared to use APA style.

For in-depth guidance on using this citation style, refer to Publication Manual of the American Psychological Association , 7th ed. We have several copies available at the MJC Library at the call number BF 76.7 .P83 2020 .

APA Style, 7th ed.

In October 2019, the American Psychological Association made radical changes its style, especially with regard to the format and citation rules for students writing academic papers. Use this guide to learn how to format and cite your papers using APA Style, 7th edition.

You can start by viewing the video tutorial .

For help on all aspects of formatting your paper in APA Style, see The Essentials page on the APA Style website.

sans serif fonts such as 11-point Calibri, 11-point Arial, or 10-point Lucida Sans Unicode, or
serif fonts such as 12-point Times New Roman, 11-point Georgia, or normal (10-point) Computer Modern (the default font for LaTeX)
There are exceptions for the title page , tables , figures , footnotes , and displayed equations .
Margins : Use 1-in. margins on every side of the page.
Align the text of an APA Style paper to the left margin . Leave the right margin uneven, or “ragged.”
Do not use full justification for student papers.
Do not insert hyphens (manual breaks) in words at the end of line. However, it is acceptable if your word-processing program automatically inserts breaks in long hyperlinks (such as in a DOI or URL in a reference list entry).
Indent the first line of each paragraph of text 0.5 in . from the left margin. Use the tab key or the automatic paragraph-formatting function of your word-processing program to achieve the indentation (the default setting is likely already 0.5 in.). Do not use the space bar to create indentation.
There are exceptions for the title page , section labels , abstract , block quotations , headings , tables and figures , reference list , and appendices .

Paper Elements

Student papers generally include, at a minimum:

Title Page (2.3)
Text (2.11)
References (2.12)

Student papers may include additional elements such as tables and figures depending on the assignment. So, please check with your teacher!

Student papers generally DO NOT include the following unless your teacher specifically requests it:

Running head
Author note

For complete information on the order of pages , see the APA Style website.

Number your pages consecutively starting with page 1. Each section begins on a new page. Put the pages in the following order:

Page 1: Title page
Page 2: Abstract (if your teacher requires an abstract)
Page 3: Text
References begin on a new page after the last page of text
Footnotes begin on a new page after the references (if your teacher requires footnotes)
Tables begin each on a new page after the footnotes (if your teacher requires tables)
Figures begin on a new page after the tables (if your teacher requires figures)
Appendices begin on a new page after the tables and/or figures (if your teacher requires appendices)

Sample Papers With Built-In Instructions

To see what your paper should look like, check out these sample papers with built-in instructions.

APA Style uses five (5) levels of headings to help you organize your paper and allow your audience to identify its key points easily. Levels of headings establish the hierarchy of your sections just like you did in your paper outline.

APA tells us to use "only the number of headings necessary to differentiate distinct section in your paper." Therefore, the number of heading levels you create depends on the length and complexity of your paper.

See the chart below for instructions on formatting your headings:

Use Word to Format Your Paper:

Use Google Docs to Format Your Paper:

Placement: The reference list appears at the end of the paper, on its own page(s). If your research paper ends on page 8, your References begin on page 9.

Heading: Place the section label References in bold at the top of the page, centered.

Arrangement: Alphabetize entries by author's last name. If source has no named author, alphabetize by the title, ignoring A, An, or The. (9.44-9.48)

Spacing: Like the rest of the APA paper, the reference list is double-spaced throughout. Be sure NOT to add extra spaces between citations.

Indentation: To make citations easier to scan, add a hanging indent of 0.5 in. to any citation that runs more than one line. Use the paragraph-formatting function of your word processing program to create your hanging indent.

See Sample References Page (from APA Sample Student Paper):

Elements of Reference List Entries: (Chapter 9)

Where to find reference information for a journal article

References generally have four elements, each of which has a corresponding question for you to answer:

Author: Who is responsible for this work? (9.7-9.12)
Date: When was this work published? (9.13-9.17)
Title: What is this work called? (9.18-9.22)
Source: Where can I retrieve this work? (9.23-9.37)

By using these four elements and answering these four questions, you should be able to create a citation for any type of source.

This infographic shows the first page of a journal article. The locations of the reference elements are highlighted with different colors and callouts, and the same colors are used in the reference list entry to show how the entry corresponds to the source.

To create your references, you'll simple look for these elements in your source and put them together in your reference list entry.

Direct Quotation of Material Without Page Numbers

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.

When to Include DOIs and URLs:

Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
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 APA Section 9.30 for more information).
If the URL is no longer working or no longer provides readers access to the content you intend to cite, try to find an archived version using the Internet Archive , then use the archived URL. If there is no archived URL, do not use that resource.

Format of DOIs and URLs:

Your DOI should look like this:

https://doi.org/10.1037/a0040251

Follow these guidelines from the APA Style website.

APA Style uses the author–date citation system , in which a brief in-text citation points your reader to the full reference list entry at the end of your paper. The in-text citation appears within the body of the paper and briefly identifies the cited work by its author and date of publication. This method enables your reader to locate the corresponding entry in the alphabetical reference list at the end of your paper.

Each work you cite must appear in the reference list, and each work in the reference list must be cited in the text (or in a table, figure, footnote, or appendix) except for the following (See APA, 8.4):

Personal communications (8.9)
General mentions of entire websites, whole periodicals (8.22), and common software and apps (10.10) in the text do not require a citation or reference list entry.
The source of an epigraph does not usually appear in the reference list (8.35)
Quotations from your research participants do not need citations or reference list entries (8.36)
References included in a statistical 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 (9.52).

Formatting Your In-Text Citations

Parenthetical and Narrative Citations: ( See APA Section 8.11)

In APA style you use the author-date citation system for citing references within your paper. You incorporate these references using either a parenthetical or a narrative style.

Parenthetical Citations

In parenthetical citations, the author name and publication date appear in parentheses, separated by a comma. (Jones, 2018)
A parenthetical citation can appear within or at the end of a sentence.
When the parenthetical citation is at the end of the sentence, put the period or other end punctuation after the closing parenthesis.
If there is no author, use the first few words of the reference list entry, usually the "Title" of the source: ("Autism," 2008) See APA 8.14
When quoting, always provide the author, year, and specific page citation or paragraph number for nonpaginated materials in the text (Santa Barbara, 2010, p. 243). See APA 8.13
For most citations, the parenthetical reference is placed BEFORE the punctuation: Magnesium can be effective in treating PMS (Haggerty, 2012).

Narrative Citations

In narrative citations, the author name or title of your source appears within your text and the publication date appears in parentheses immediately after the author name.

Santa Barbara (2010) noted a decline in the approval of disciplinary spanking of 26 percentage points from 1968 to 1994.

How to cite in APA Style (7th edition)

(Looking for the old 6th edition guide?)

Most academic writing cites others' ideas and research, for several reasons:

Sources that support your ideas give your paper authority and credibility
Shows you have researched your topic thoroughly
Crediting sources protects you from plagiarism
A list of sources can be a useful record for further research

Different academic disciplines prefer different citation styles, most commonly APA and MLA styles.

Besides these styles, there are Chicago , Turabian , AAA , AP , and more. Only use the most current edition of the citation style.

Ask your instructors which citation style they want you to use for assignments.

The basics of apa.

We’re going to start from the beginning for all of you newbies out there, or for those of you looking for a refresher.

APA is an abbreviation which stands for American Psychological Association. This is a massive organization, responsible for creating and sharing psychology-related publications, research, and databases.

Basically, they keep psychologists and other similar roles in the loop with what’s happening in the world of psychology. With close to 120,000 members, this is THE leading world organization related to psychology.They are not officially associated with this guide, but the information here talks about their citing format and rules in depth.

Why were APA citations created and why did my teacher ask me to use this style?

Are you scratching your head, wondering what is APA style is and how this all relates to your research project? To make a long story short, the American Psychological Association did something really cool. Back in 1952, they created a way for ALL psychology researchers to structure their citations. This standard method did three things:

Psychology researchers were all able to display the sources they used in a systematic way.
Readers were able to easily understand the information shown in citations.
There was enough information displayed in the citations for readers to go out and find the exact sources on their own.

APA citations were such a hit, they were so good, that other science disciplines soon adopted the citation format as well. In fact, other disciplines outside of the science world use APA style today, too. So, whether you’re creating a psychology-related research project or not, there’s a good chance you were asked to create your citations in APA style.

Currently in its 7th edition, the Publication Manual of the American Psychological Association is one of the most frequently used style guides for academic writing today!

With the 7th edition just coming onto the scene in 2020, the American Psychological Association does not expect to see widespread usage of the 7th edition until later in 2020. This is why you should always double-check with your teacher on whether they want you to use the 6th edition or the 7th edition for your projects.

Click here for more basics on this style.

Another widely used style is MLA format . Believe it or not, there are thousands of other styles, so perhaps your teacher or professor requested a completely different one. If you’re in that boat, head to EasyBib.com to check out more styles . While you’re at it, poke around and check out our APA reference generator. It may be just what you’re looking for.

References vs. Citations – What’s the difference?

References and citations are two terms that are thrown around a lot and quite often mean the same thing. A reference, or citation, shows the reader that a piece of information originated elsewhere. But, along came APA and decided to throw a curveball at us. In APA, the two terms have two different meanings.

A citation is found in the actual writing of an APA research paper.

In-text citation example:

“Lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small” (Einstein, 2007, p. 5).

A reference is found on the reference page, which is the last page of a research paper.

Reference Page Example:

Einstein, A. (2007). The world as I see it. Google Books. https://books.google.com/books?id=aNKOo94tO6cC&source=gbs_navlinks_s (Original work published 1934)

The information included in an APA citation is just a snapshot of the information found in the full reference. For more information on when it’s appropriate to include a citation in your paper, head to section 8.1-8.10 of the Publication manual.

Now, what makes things even trickier is that most teachers and professors use the term “APA citations” when they’re actually talking about the full references. How many times have you heard your teacher say, “Make sure you have your citations on the last page!”

Eek! So, to stay on the same page as your teacher, this guide shows you how to make references for an APA reference page, but we’re calling the page “APA Citations.” Someone’s gotta give in, right? Looks like it’s us.

If you’re looking for a quick read on the citations found in the body of the paper, check out our APA Parenthetical Citation page. It’s just one of the many free APA citation guides available on EasyBib.com. Need an APA citation generator? You can find one at EasyBib.com as well!

A rundown on references

Before we get into the nitty-gritty details on how to structure references for your APA paper, let’s get one more quick piece of information off the table.

References are added to research papers and projects only when a source is included in the writing itself.

We don’t add references to a reference page if we want to simply suggest other, similar titles. No! We create references when an actual piece of information from another source is added into the project.

Does your paper include a piece of data from a report? Great! You copied a line of text from a case study and put it in your project (with quotation marks around it)? Perfect! You included a bar graph you found in a brochure? Fantastic! Make sure you create an APA citation in the text of your paper and include the reference on the final page.

The only exception to the above rule is if you’re creating an “annotated bibliography.” For more on that, check out our APA annotated bibliography page.

In case you were wondering, the same goes for MLA in-text & parenthetical citations on the MLA works cited page.

Ready to get started? The next section of the guide is going to explain, step-by-step, how to structure every nook and cranny of your references.

But, if you’re dreaming of an APA citation maker to help make the pain go away from building your references from scratch, you’re in luck. EasyBib.com has an APA citation maker! In just a few clicks, our technology structures and styles each and every APA citation for you. If you don’t know much about it, head to the EasyBib homepage to learn more.

Fundamentals of an APA citation

This entire section goes into detail on each component of a reference. If you’re looking to learn how to style the names of the authors, the title, publishing information, and other aspects related to the reference, this section is for you!

If you want to skip the small talk and see an APA style paper example, go to the “Citation Resources” menu on this page and select “APA Format Guide.” It includes a title page example, an APA paper example, and an APA reference page example.It’s all there for you and the best part about it is it’s free! Do yourself a favor and take a peek at it now!

Author information

The very first piece of information in most references is the author’s name(s). We say “most,” because some sources may not have an author (such as websites, the Bible…). If your source doesn’t have an author, do not include any information about an author in your reference.

Citing a Source with 1 Author

Apa structure:.

Last name of the Author, First initial. Middle initial.

APA Example:

To see some examples, scroll down to the bottom half of this page.

Citing a Source with 2 Authors

Does your source have two authors? Do not put the names in alphabetical order. They should be written in the order they’re displayed on the source.

Last name of the 1st listed Author, First Initial. Middle Initial., & Last name of the 2nd listed Author, First initial. Middle initial.

Doe, J. B. & Chen, W. I.

For an example of a reference with two authors according to the 7th edition of the Publication manual , scroll down to the “Journal Articles found in Print” section, or check out section 9.7-9.12 in the Publication manual.

Citing a Source with 3 to 20 Authors

Does your source have three to twenty authors? The American Psychological Association has made some updates on how to list multiple authors in your citations. If you have between three to twenty authors, list all the authors names (Last Name, Initials). Put them in the same order they’re listed in the source. Commas separate names, and put an ampersand right before the last name.

Bos, G., Hajek, S., Kogman-Appel, K., & Mensching, G. (2019). A Glossary of Latin and Italo-Romance Medico-Botanical Terms in Hebrew Characters on an Illustrated Manuscript Page (Ms. Oxford, Bodleian Opp. 688, fol. 177b). Aleph: Historical Studies in Science and Judaism 19 (2), 169-199. https://www.muse.jhu.edu/article/747571

Citing a Source with 21+ Authors

If your source has over twenty authors, list the last name and initials of the first 19 authors, placing a comma between each name. After the name of the 19th author, use an ellipsis in place of the remaining authors’ names. Then, list the final author’s name in front of it.

Here’s a formatting example for 21+ names using the U.S. presidents (this is NOT a reference example):

Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J., Taylor, Z., Fillmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., … Trump, D. J.

Citing an Author that is an organization or company

If your source is written by an organization or company:

Some sources are written and released by companies, not necessarily individual people. For example, most brochures at museums only display the institution’s name. Advertisements also only show the company’s name. If the source you’re attempting to cite only shows a group or organization’s name, place it in the reference in the place you’d normally include an individual person’s name.

Write out the name of the group in full; do not use abbreviations. For example, it may seem okay to use USDA, but APA writing style prefers you write out United States Department of Agriculture.

If you’re looking for information on how to style your own name in APA headings, find the example paper on EasyBib.com.

Formatting Titles & Dates

Formatting the date of publication.

The date the source was published is the next item shown in a reference. It’s directly after the author’s name.

For the majority of sources, include only the year in parentheses.

If you’re citing an article in a magazine, include the year and the month.

Peterzell, J. (1990, April). Better late than never. Time, 135 (17), 20–21.

Check out the examples towards the bottom of the page, or head to sections 9.13-9.17 of the Publication manual to see how dates are displayed.

Title rules and capitalization

Titles are the next piece of information shown in a reference. Titles are often tricky for people to style. Students often wonder, “Should I type out the title as it’s shown on the source?” “Should the title be written in italics or underlined?” Here are the answers to (hopefully) all of your title-related questions:

Which letters are capitalized?

Most titles are written with a capital letter in these places:

At the beginning of the title
At the beginning of a proper noun
At the beginning of the subtitle

It may be tempting to write the title as you see it shown on the source, or with capital letters at the beginning of every important word, but that’s not how APA referencing does it.

Here are a few examples of proper lettering:

A star is born
Spider-Man: Into the spiderverse
Harry Potter and the deathly hallows

The only source types that are written with a capital letter at the beginning of every important word are periodicals. Some examples include the titles of newspapers, journals, and magazines.

The New York Times
School Library Journal,

How should I style the title?

Anything that stands alone is written in italics. When we say “stands alone,” we mean it isn’t part of a larger collection. Most books are a single source, so they’re written in italics. Other examples include movies, brochures, dissertations, and music albums.
Sources that are part of a collection are written without italics. Website pages, journal articles, chapters in books, and individual songs (from an album) are written without italics.
Remember, the styling information above is for the APA reference page only! Citations in the text of the paper are styled differently. If you need to see a full APA sample paper, check out the other resources on EasyBib.com!

Check out some of the examples below to see how the titles are typed out and styled. You can also head to section 9.18-9.22 of the Publication Manual for more details

If it’s not the actual title, but an APA title page for your paper that you need help with, check out the Title Page APA creator on the homepage of EasyBib.com! Or, check out the main guide for this style, which includes an APA cover page template.

Additional information about a source

It can be difficult to understand a source type just by looking at an APA style citation. Sometimes it isn’t clear if you’re looking at a citation for a presentation, a blog post, lecture notes, or a completely different source type.

To clear up any confusion for your reader, you can include additional information directly after the title. This additional information about the source type is written in brackets with the first word having a capital letter.

Wilson, T. V. & Frey, H. (2019, May 13). Godzilla: The start of his story [Audio podcast]. iHeart Radio. https://www.missedinhistory.com/podcasts/godzilla-the-start-of-his-story.htm

Thanks to the information in the brackets, the reader can easily see that the source is an audio podcast.

Check out the various examples towards the bottom of this page.

Publication information

Publication information includes the name of the publisher. In most cases, the publication information is only included for print sources. Check out the book reference below to see the publication information in action.

Citing a chapter in an edited book in print in APA

An edited book is one that was compiled by an author. Each individual chapter, or section, is written by someone else. Since you’re probably citing the specific chapter, rather than the whole entire book, place the name of the chapter’s author in the first position.

Chapter Author’s Last Name, F. M. (Year published). Chapter title. In F. M. Editor’s Last Name (Ed.), Title of book (Xrd ed., pp. x-x). Publisher.

Citing The Bible in APA

Since the bible is considered a “classical work,” and widely known, it is not necessary to create a full reference. Only include a citation in the text of the paper.

Two items need to be included:

The title and version of the source, such as the New Living Bible
The names, verses, chapters, or any numbers associated with the section you’re referring to.

“Then the king asked her, “What do you want, Esther? What is your request? I will give it to you, even if it’s half the kingdom” (Esther 5:5 New Living Translation).

Citing a Source on the Internet in APA

Citing digital sources in this style is much easier than other styles. If you’re wondering why, it’s because a lot of information isn’t included in the reference.

For most digital sources, only five items are usually needed:

The name of the author
The date the source was published
The title of the source
The medium (blog post, audio file, pdf, etc.)
The website address

Here’s some more information related to web content:

Only include the medium if it’s unique or if it will help the reader understand the source type.
Include the website address at the end of the citation.
Do not place a period at the end of the website address.

Have a digital source? Need to cite APA? Check out some of the examples below.

Citing online encyclopedias & dictionaries – Group author

If you conducted or watched a personal interview and the transcript or audio is not available for the reader, then there really isn’t any point to create a full reference. These types of sources are not recoverable and the reader would be unable to find the interview on their own. Instead, only create a citation in the text of the paper. Use the first initial, middle initial, and last name of the person being interviewed, along with “personal communication,” and the date of the interview.

Institution or organization name. (n.d.). Entry title. In Title of Website or reference . Retrieved Month Day, Year, from URL

Merriam-Webster. (n.d.). Doleful. In Merriam-Webster.com dictionary. Retrieved March 1, 2020, from https://www.merriam-webster.com/dictionary/doleful

Citing online encyclopedias & dictionaries – Known author

If there is a known author, cite the source this way:

Last name, F. M. (Date published). Entry title. In F. M. Last name (ed.), In Title of Website or reference . Retrieved Month Day, Year, from URL

Mann, M. E. & Selin, H. (n.d.). Global warming. In Encyclopaedia Britannica . Retrieved March 1, 2020, from https://www.britannica.com/science/global-warming

Citing Wikipedia

Cite a Wikipedia page just like a normal webpage, but use an archived version. Go to the “View history” tab at the top of a Wikipedia page to find these archived versions, their publishing date, and their URL.

Article title. (Year, Month Day). In Wikipedia . URL

Citing Media Sources in APA

Citing a song or music listened to online in apa.

Modern songs (e.g., that song you heard on the radio this morning) should list the name of the recording artist’s name. Classical music lists the song’s composer (e.g., think Mozart, Beethoven, etc.).

Note: include a URL in the reference if that location is the only means of retrieval (like if they only post their music to SoundCloud or on their own specific website). If the song is available across multiple platforms, no URL is needed.

APA Structure for a modern song:

Artist’s Last Name, F. M. (Year published). Song’s title [Song]. On Title of album . Publisher(s).

Grande, A. (2019). 7 rings [Song]. On thank u, next . Republic Records.

APA Structure for a classical song:

Artist’s Last Name, F. M. (Year published). Song’s title [Song recorded by Artist’s Name]. On Title of album . Publisher.

Bach, J. S. (1997). Toccata and Fugue in D minor [Song recorded by William McVicker]. On Great organ classics. Sony Music Entertainment UK Limited.

Sheet music in APA

To cite APA sheet music, cite it exactly the same as a book. If it’s found online, cite it as a website.

Citing streamed videos in APA

Use this format if you’re citing a video found online (such as an APA citation for a YouTube video ).

Person who posted the video’s Last Name, F. M. [Username]. (Year, Month Day of posting or publishing). Video’s title [Video]. URL

Vliegenthart, S. [booksandquills]. (2018, December 3). Books from uni we didn’t hate [Video]. YouTube. https://www.youtube.com/watch?v=9G52GCgpEZg

If the name of the individual isn’t available, start with the username, and remove the brackets.

APA Examples:

Chegg. (2018, November 15). One common grammar error to avoid [Video]. YouTube. https://www.youtube.com/watch?v=5Bfx50f853g

Maroon 5. (2018, May 30). Girls like you ft. Cardi B [Video]. YouTube. https://youtu.be/aJOTlE1K90k

Solution #1: How to cite a photo with no creator, date, or title in APA

Describe the photo and place brackets around it.
Add “n.d” with parentheses around it.
List where the reference was found without italics.
Follow with the URL information of where you found the photo if it was found online.

Example of a photo citation with no creator, date, or title

[Photograph of two hens in a barn]. (n.d). Theoretical Prints. http://Theoretical_Prints.org/two-hypothetical-hens/

Solution #2: How to cite a dictionary entry in APA

Dictionary entry in print

List the organization or the author’s name in last name, first name initial, and middle name initial (if there is one) with a period following.
Use n.d if the date is not listed.
List the name of the dictionary term. Capitalize the first letter and use a period after.
Write “In” followed by the name of the dictionary used. The dictionary name should be italicized.
In parentheses, write the volume abbreviated as “Vol.” followed by the volume number and page number. Add a period after it.

Examples for a printed dictionary entry citation

Hypothetical Association of Learning. (2014). Cake. In The Hypothetical Learner’s Dictionary (Vol. 2, p. 3).

Johnson, C. K. (2014). Cake. In The Hypothetical Learner’s Dictionary (Vol. 2, p. 3).

Dictionary entry from an online source

Use “n.d” if the date is not listed.
Write the name of the dictionary in italics and follow it with a period.
Write “Retrieved” then the date you accessed the entry online in this format: Month Day, Year. End it with a comma.
Write “from” and add the page URL.

Examples for an online dictionary entry citation

Hypothetical Association of Learning. (2014). Cake. In The Hypothetical Learner’s Dictionary. Retrieved November 7, 2021, from https;//dictionary.hypothetical.org/dictionary/English/cake

Johnson, C. K. (2014). Cake. In The Hypothetical Learner’s Dictionary. Retrieved November 7, 2021, from https;//dictionary.hypothetical.org/dictionary/English/cake

Solution #3: How to ensure that an auto-generated citation in APA style is correct

Ensure that the correct number of people are accredited by counting the names in the source and the website citation.
Ensure that all names are spelled correctly.
If 2-20 authors are used, ensure that an ampersand is used before the last name.
If more than twenty authors are used, ensure that an ellipsis is used before the final author.
Check to make sure that the date is correct and that the month or year do not need to be adjusted.
Generally, works cited as a whole, such as books, are written in italics, while shorter works that are part of a bigger work, such as a chapter in a book or articles from a periodical (e.g., journal, magazine, newspaper, etc.), are usually in regular font.
The title of webpages are italicized, while the title of the site they are on is in regular font.
Social media post citations use the written post content (up to 20 words) as the title. This “title” should be italicized.
If using a chapter, make sure that the editor is accredited.
If using an article, make sure that the journal number is italicized and that the volume number is in parentheses.
Make sure that your links are active and that they bring you to the correct location. You may need to rewrite the link.

Learning Objectives

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

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

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

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

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

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

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

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

General Formatting Guidelines

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

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

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

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

The title page of your paper includes the following information:

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

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

Beyond the Hype: Evaluating Low-Carb Diets cover page

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

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

Exercise \(\PageIndex{1}\)

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

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

Margins, Pagination, and Headings

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

Use these general guidelines to format the paper:

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

Exercise \(\PageIndex{2}\)

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

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

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

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

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

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

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

Exercise \(\PageIndex{3}\)

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

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

Citation Guidelines

In-text citations.

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

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

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

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

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

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

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

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

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

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

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

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

writing at work

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

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

References List

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

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

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

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

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

Key Takeaways

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

In-Text Citations: The Basics

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.

Note: This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019. The equivalent resource for the older APA 6 style can be found here .

Reference citations in text are covered on pages 261-268 of the Publication Manual. What follows are some general guidelines for referring to the works of others in your essay.

Note: On pages 117-118, the Publication Manual suggests that authors of research papers should use the past tense or present perfect tense for signal phrases that occur in the literature review and procedure descriptions (for example, Jones (1998) found or Jones (1998) has found ...). Contexts other than traditionally-structured research writing may permit the simple present tense (for example, Jones (1998) finds ).

APA Citation Basics

When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998). One complete reference for each source should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication and not the page number in your in-text reference.

On the other hand, if you are directly quoting or borrowing from another work, you should include the page number at the end of the parenthetical citation. Use the abbreviation “p.” (for one page) or “pp.” (for multiple pages) before listing the page number(s). Use an en dash for page ranges. For example, you might write (Jones, 1998, p. 199) or (Jones, 1998, pp. 199–201). This information is reiterated below.

Regardless of how they are referenced, all sources that are cited in the text must appear in the reference list at the end of the paper.

In-text citation capitalization, quotes, and italics/underlining

Always capitalize proper nouns, including author names and initials: D. Jones.
If you refer to the title of a source within your paper, capitalize all words that are four letters long or greater within the title of a source: Permanence and Change . Exceptions apply to short words that are verbs, nouns, pronouns, adjectives, and adverbs: Writing New Media , There Is Nothing Left to Lose .

( Note: in your References list, only the first word of a title will be capitalized: Writing new media .)

When capitalizing titles, capitalize both words in a hyphenated compound word: Natural-Born Cyborgs .
Capitalize the first word after a dash or colon: "Defining Film Rhetoric: The Case of Hitchcock's Vertigo ."
If the title of the work is italicized in your reference list, italicize it and use title case capitalization in the text: The Closing of the American Mind ; The Wizard of Oz ; Friends .
If the title of the work is not italicized in your reference list, use double quotation marks and title case capitalization (even though the reference list uses sentence case): "Multimedia Narration: Constructing Possible Worlds;" "The One Where Chandler Can't Cry."

Short quotations

If you are directly quoting from a work, you will need to include the author, year of publication, and page number for the reference (preceded by "p." for a single page and “pp.” for a span of multiple pages, with the page numbers separated by an en dash).

You can introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

If you do not include the author’s name in the text of the sentence, place the author's last name, the year of publication, and the page number in parentheses after the quotation.

Long quotations

Place direct quotations that are 40 words or longer in a free-standing block of typewritten lines and omit quotation marks. Start the quotation on a new line, indented 1/2 inch from the left margin, i.e., in the same place you would begin a new paragraph. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation 1/2 inch from the new margin. Maintain double-spacing throughout, but do not add an extra blank line before or after it. The parenthetical citation should come after the closing punctuation mark.

Because block quotation formatting is difficult for us to replicate in the OWL's content management system, we have simply provided a screenshot of a generic example below.

This image shows how to format a long quotation in an APA seventh edition paper.

Formatting example for block quotations in APA 7 style.

Quotations from sources without pages

Direct quotations from sources that do not contain pages should not reference a page number. Instead, you may reference another logical identifying element: a paragraph, a chapter number, a section number, a table number, or something else. Older works (like religious texts) can also incorporate special location identifiers like verse numbers. In short: pick a substitute for page numbers that makes sense for your source.

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference and may omit the page numbers. APA guidelines, however, do encourage including a page range for a summary or paraphrase when it will help the reader find the information in a longer work.
