Properly formatted APA citations include two main elements: the reference list entry and the in-text citation. Below you will find sample citations for a variety of commonly-used reference types. For additional questions, consult the Publication Manual of the American Psychological Association (7th ed.)[1]

Reference List

The reference list is found at the end of your document, and it includes all of the sources used when developing your paper or project. References are listed in alphabetical order by the author’s last name, and each reference will have a hanging indent to make it easier to visually distinguish between each reference.

No Author

If there is no author, the title moves into the place of the author. The reference should then be alphabetized by the first word in the title within the reference list. If the first word is an article (“a,” “an,” or “the”), alphabetize according to the second word. If the first word is a number, alphabetize according to the spelling of the number. (For example, if the first word is “665,” you would alphabetize it as if it were “six-hundred and sixty-five.”

Example

Down the Line. (1895). In The Olio: An Annual (pp. 54-58). The Corps of Cadets of the Agricultural and Mechanical College of Texas.

Single Author

In APA style, when there is a single author, you should list them with the last name first, followed by the first and (if available) middle initial.

Example

Clark, D. T. (2009). Lending Kindle e-book readers: First results from the Texas A&M University project. Collection Building, 28(4), 146-149. https://doi.org/10.1108/01604950910999774

Two Authors

When there are two authors, list both and connect them with an ampersand (&). Be sure to keep the authors in the order in which they appear on the source.

Example

Rutledge, L., & LeMire, S. (2016). Beyond disciplines: Providing outreach to underserved groups by demographic. Public Services Quarterly, 12(2), 113–124. https://doi.org/10.1080/15228959.2016.1157565

Three to Twenty Authors

When there are between three and twenty authors, list each one and use an ampersand (&) before the final author. Be sure to keep the authors in the order in which they appear on the source.

Example

LeMire, S., Graves, S. J., Hawkins, M., & Kailani, S. (2018). Libr-AR-y Tours: Increasing engagement and scalability of library tours using augmented reality. College & Undergraduate Libraries, 25(3), 261–279. https://doi.org/10.1080/10691316.2018.1480445

Twenty-One or More Authors

When there are more than twenty authors, list the first nineteen authors, then add an ellipsis (…) and the last author’s name. The ellipsis (…) will take the place of author names between author number nineteen and the final author. Be sure to keep the authors in the order in which they appear on the source.

Example

Agnese, R., Anderson, A. J., Asai, M., Balakishiyeva, D., Thakur, R. B., Bauer, D. A., Beaty, J., Billard, J., Borgland, A, Bowles, M.A., Brandt, D., Brink, P.L., Bunker, R., Cabrera, B., Caldwell, D.O., Cerdeno, D.G., Chagani, H., Chen, Y., Cherry, M., … Zhang, J. (2014). Search for low-mass weakly interacting massive particles with SuperCDMS. Physical Review Letters, 112(24), 241–302. https://doi.org/10.1103/PhysRevLett.112.241302

Institutional Author

Sometimes the author isn’t a person—instead, the source is authored by an organization. In this case, you’ll list the organization as the author.

Example

Texas A&M University. (2019). Aggie traditions. https://www.tamu.edu/traditions/index.html

Book

Books list the author, followed by the year, and then the title in italics. The title is in sentence case, which means that you only capitalize the first word, any proper nouns or adjectives, and the first word after a colon or period. APA also includes the publisher name. If the book is accessed electronically, also include the digital object identifier (doi). Figure 12.1[2] illustrates the components of a book citation in APA format.

Example

This description box shows the following book citation in APA style: Dromgoole, G. (2005). Aggie savvy : practical wisdom from Texas A&M. State House Press. The elements, in order, are author's last name, comma, space, author's first initial, period, space, open parentheses, year of publication, close parentheses, period, space, title of work with only first word and any proper nouns capitalized, period, space, publisher, period. The citation is formatted on the page using a hanging indent. Screen Reader Tip: When working with bibliographic citations, set your screen reader to read by character. This step will help you make sure you get all the capitalization and punctuation in the right places.
Figure 12.1: Book Citation in APA 7 Style

Article from a Database

Articles from online databases like Google Scholar or EBSCO include the author names, year of publication, and article title in sentence case. For the journal title, follow the capitalization provided by the journal itself. The journal title and the volume number are in italics. The issue is in parentheses, followed by the page range.

To help the reader access the article, always include the doi (permanent url) if one is available. It is generally listed near the top of the article. It may appear as doi: or https://dx.doi.org/ followed by a sequence of numbers and/or letters. The doi number typically starts with the number 10, as in the example below. If there is a doi available, include it in your citation using the format https://doi.org/[insert doi number]. Figure 12.2[3] illustrates the components of a journal article citation in APA format.

Example

This description box shows the following journal article citation in APA style: Rutledge, L., & LeMire, S. (2016). Beyond disciplines: Providing outreach to underserved groups by demographic. Public Services Quarterly, 12(2), 113-124. https://doi.org/10.1080/15228959.2016.1157565. As you can tell, journal articles are a bit more complicated than books. The elements of the citation, in the correct order, are as follows: first author's last name, comma, space, first author's first initial, period, comma, space, ampersand, space, second author's last name, comma, second author's first initial, period, space, open parentheses, year of publication, close parentheses, period, space, title of article with only the first word and any proper nouns capitalized, period, space, title of journal or its abbreviation italicized with all important words capitalized, comma, space, volume number, open parentheses, issue number, close parentheses, space, page numbers, period, space, URL, period. The citation is formatted on the page using a hanging indent. Screen Reader Tip: When working with bibliographic citations, set your screen reader to read by character. This step will help you make sure you get all the capitalization and punctuation in the right places.

Newspaper Article

If a newspaper article is found in a database such as Newspaper Source or Access World News, do not include the database name or URL. If the article is found through the open web, include the URL.

If an article is from an online newspaper (for example, Washington Post, New York Times, Wall Street Journal), italicize the name of the newspaper. If the article is from an online news website (e.g. BBC News, CNN, Reuters), italicize the name of the article and not the site.

Example from an online newspaper

Boren, C. (2018, November 25). It took seven overtimes for Texas A&M to beat LSU in the craziest college football game of the year. Washington Post. https://www.washingtonpost.com/sports/ 2018/11/25/it-took-seven-overtimes-texas-am-beat-lsu-craziest-college-football-game-year/

Example from an online news website

Holcombe, M. (2019, July 18). Texas A&M’s new program opens the door to college education for students with disabilities. CNN. https://www.cnn.com/2019/07/18/us/texas-am-program- disabilities/index.html

Website

Example

Texas A&M University Division of Student Affairs. (2019). Residence life. https://reslife.tamu.edu/

YouTube Video

Example

Texas A&M University. (2019, September 8). Fearless on every front [Video]. YouTube. https://www.youtube.com/watch?v=YlRup0e8kTk

Interview

In APA format, an unpublished interview is not included in the reference list. This is because the interview is not available for the reader to view. Instead, interviews are cited only in-text.

Lecture

In APA format, if you are citing your professor’s lecture slides or content, you should point the reader to a digital copy of that content if possible. If housed in a course management system, direct the reader to the login page for that system.

Example

Pantuso, T. (2019, September 10). Visual rhetoric [PowerPoint slides]. eCampus. https://ecampus.tamu.edu/

In-Text Citations

APA in-text citations use the last name(s) of the author(s), followed by a comma and the year of publication. If using a direct quotation, also include the page number where that quotation can be found. The abbreviation “p.” precedes any page numbers. These items are all separated by commas.

In APA format, you can also embed the in-text quotation directly into your sentence (for example, Smith (2001) found that…), which then obviates the need for a parenthetical at the end of the sentence, except in the case of a direct quotation.

No Author

As with the reference list, the in-text citation will use the title if there is no author available. Use the first few words of the title if it is long, and place it in quotation marks.

Example

(“Down the Line,” 1895).

Single Author

If the work has a single author, use the author’s last name, followed by a comma and the year of publication.

Example (no direct quotation)

(Clark, 2009)

Example (direct quotation)

(Clark, 2009, p. 42)

Two Authors

When there are two authors, list the last names of both connected by an ampersand (&). Be sure to keep the authors in the order in which they appear on the source.

Example

(Rutledge & LeMire, 2016).

Three or More Authors

When there are three or more authors, list the first author’s last name, followed by et al. This is a Latin phrase meaning “and others” and used in some citation formats as a way to abbreviate a list of names. Notice that the switch to “et al.” occurs after three authors when using in-text citations. In your References list, you will include up to twenty authors.

Example

(Tribble et al., 2002).

Institutional Author

As with the reference list, you’ll list the organization as the author in the in-text citation.

Example

(Texas A&M University, 2019).
