How Do I Cite in APA?

APA Citation

Citing Sources in the Text

  • You must provide an in-text citation when quoting or paraphrasing someone else’s work
  • In-text citations direct the reader to the source’s entry in the reference list
  • When using APA format, follow the author/date method of in-text citations

Examples

Author not named in text
One critic of Milgram’s experiments insisted that the subjects “should have been fully informed of the possible effects on them” (Baumrind, 2003, p. 34).

Author named in text
Baumrind insisted that the subjects in Milgrim’s study “should have been fully informed of the possible effects on them” (2003, p. 34).

Two authors
One study demonstrates that "non medical needs may be addressed by anyone on the team" (Csikai & Chaitin, 2006, p. 112).

Three or more authors

Only the first author's name, followed by "et al." is necessary. 

(Smith et al., 2003)

Smith et al. (2003) argue...

If you are citing multiple works by the same group, or similar group, of authors, listing only the first author would create ambiguity. If this is the case, you'll need to write out more names. For example, if you were citing works with these authors:

Pepinsky, Rentl, Lu, Corson, and Lee (2001)

Pepinsky, Rentl, Stanton, Johnson, and Randall (2001)

They would be cited in-text as follows to avoid ambiguity:

(Pepinsky, Rentl, Lu, et al., 2001)

(Pepinsky, Rentl, Stanton, et al., 2001)

Note: since et al. is plural, it should always replace more than one name. If et al. would stand in for only one author name, write out that author's name instead.

 

Tips

  • Anonymous works are referred to by full or shortened title.
               Example: ("Study Finds," 1982).
  • When an information source contains no page numbers, you should try to include information that will assist your readers in finding the passage being cited. Use the heading or section name, an abbreviation of the heading/section name, or a paragraph number (para. 1), or a combination.
               Example: One website describes the side effects of this drug (King, 2005, para. 2).

Preparing the Reference list

Your reference list should include all the sources you quoted, paraphrased, or summarized in your assignment. This listing appears at the end of your assignment. When formatting your references, follow these standards:

  1. Arrange your sources in alphabetical order by the last name of the author or by title if no author exists.
  2. Double space the entire list (both within and between entries).
  3. Indent the second and subsequent lines of each entry five to seven spaces from the left.
  4. Type the article title in sentence case and the journal title in title case.
  5. Italicize the journal title and volume number.
  6. Include the issue number in parentheses if the journal is paginated by issue.

Avoiding Plagiarism Checklist

  • Is each use of someone else’s material noted in your assignment?
  • Did you reference your sources for graphs, statistics and other borrowed data?
  • Are quotations from another persons’ work exact? Did you use quotation marks?
  • If you paraphrased or summarized someone else’s material did you use your own words and sentence structure?
  • Does your works cited include all the sources you referred to in your assignment?
