Citation Guide

Discover and explore the basics of why and how to cite.

Overview

APA Citation Style

Disciplines within the Social Sciences typically use the Publication Manual of the American Psychological Association (APA) as the preferred style of citation.  This style is used when citing materials, creating a bibliography or setting up the structure of a research paper for assignments. 

The examples give an overview of APA citation style for in-text citation and the reference list at the end of the paper.

APA Article (Academic Journal & Magazine) Citation

Journal Article Basic Format:

AuthorLastName, FirstInitial. (Year). Title of article. Title of JournalVolume(Issue), Pages.

Retrieved from URL

  • Italicize the Journal Title, and Volume.
  • Article Title Capitalization: Capitalize only the first word of the article's title, the first word of the subtitle, proper nouns, and acronyms. 
  • DOI: When the article was accessed online, include the DOI (Digital Object Identifier), when available. Not all articles have a DOI.
  • URL: Include the URL only if the article does not have a DOI. APA does not require you to include the proxy server information (i.e. library.limestone.edu:2048/login?url=) as a part of your URL, but note that removing this information also removes the "Persistent Link" to the article in Limestone's database subscription. Use this formula: Retrieved from http://www.xxxxxxxx

APA In-text Citation & Quotations

APA uses an author-date citation style. To correctly use APA, a short in-text citation is used consisting of the author's last name and the year of publication. A full citation is included on the References list.

Basic Format

(AuthorLastName, Year). When a page number is included: (AuthorLastName, Year, p. #).

APA style prefers that the name of the author who is being cited should be included in the text of the sentence itself. If both the author and year of publication are stated in the sentence, no additional parenthetical citation is required (unless a page reference is included).

When to include a page number: If a direct quotation is included, a page reference (when available) must also be included in the in-text citation. Although not explicitly required, APA encourages the inclusion of page numbers for paraphrased passages or other direct references. 

Examples: 

  • Preferred APA in-text citation style (where no page number is required/included): 

Parker (2018) argues that colleges should require students to carry computers to class.

  • Preferred APA in-text citation including a direct quotation (in which case a page reference is required):

According to Parker (2018), "students who own laptops perform better on average in their courses than those who do not own their own computers" (p. 198). 

  • Notice that page references follow the close parenthesis, even when the sentence does not end:

According to Parker (2018) "students have a responsibility to care for their equipment" (p. 121), which she also notes is not always a top priority for every student.

  • An in-text citation where the author's name is not mentioned:

Additionally, she stated, "most students are perfectly responsible" (Jones, 2018, p. 121).


Works by Multiple Authors

Two Authors: 

For works by two authors, include both names in alphabetical order, including an "&" between them.

Parenthetical: (Jones & Smith, 2011). 

In a sentence: According to Jones & Smith (2011), . . . 

Three to Five Authors: 

For works by three to five authors, include all the authors' names the first time only. E.g., (Dexter, Hardwick, Jones, McMillan, & Smith, 2018).

In subsequent mentions of the same author, use et al. in place the second, third, fourth and fifth names.

Parenthetical: (Dexter et al., 2018)

In a sentence: According to Dexter et al. (2018), . . . 

et al. (et alia) is Latin for "and others," and is used to avoid printing all the names of the authors of a source. A period does not follow "et," only "al."

Six or More Authors:

If a work has six or more authors, use et al. from the first time the source is cited. See the section on three or more authors above.

E.g. (Kim et al., 2017)


Long Quotations 

Although it is best to avoid long quotations in an APA paper, if you include a quotation of more than 40 words, it must be included in a separate block of text. Indent the entire block quotation by one-half inch (the same as the standard tab indent), maintain double-spacing, and place the citation at the end in parentheses after the period or punctuation from the quotation. Do not include quotation marks. In good APA style, the quoted author should be introduced before the quotation begins.

Example:

According to Kim et al. (2017): 

Lorem ipsum dolor sit amet, consectetur adipiscing elit. In laoreet orci sit amet facilisis aliquet. Morbi tristique porttitor diam, pellentesque rhoncus tortor sagittis commodo. Vestibulum tempus vehicula varius. Cras nibh neque, elementum ac luctus eget, semper quis est. Etiam sit amet sapien porta, pretium dui sed, sagittis nibh. Suspendisse non pellentesque diam, et accumsan mauris. Aliquam volutpat vel risus pharetra mattis. Aenean in justo imperdiet, rutrum ligula in, pellentesque tellus. Praesent a turpis at sem fringilla accumsan. Cras pellentesque ut massa at laoreet. Ut vestibulum id metus quis tincidunt. Sed sollicitudin elit nec quam volutpat faucibus a eu purus. Curabitur vulputate sit amet nibh a mollis. Suspendisse blandit libero quis eros mattis blandit. Morbi maximus elit eget sapien feugiat, non luctus magna rutrum. In suscipit, quam vel efficitur placerat, metus dolor sollicitudin odio, a dignissim justo libero eu velit. (p. 110)

The remainder of the paper continues as normal. . . .
