Citation Style

Authors' Names: In-Text Citations (APA 7th ed.)

Two authors

  • If the authors' names are in your sentence, use and between their last names.
  • If the authors' names are in your parenthetical citation, use & between their last names.
  • Add the year and page numbers (if there are any). 

Examples:

  • A recent study examined the impact of citations in medical literature (Pence & Chapman, 2017).
  • Pence and Chapman (2017) wrote a definitive work on citation style.

Three or more authors

  • Include the name of only the first author plus “et al.” in every citation. Add the year and page numbers (if there are any). For example:
    (Emerson et al., 1993, p. 76)

No author

  • Include the title and year of publication. If the title is long (more than 3 words), shorten it.
  • If the title of the work is not italicized in the reference (article, book chapter, page or section on a website), use the first word or two of the title in quotation marks.
  • If the title of the work is italicized in the reference (book, entire website), use the first word or two of the title in italics.
  • For example, if you had an article with the title Practical oral care for people with intellectual disability, the parenthetical citation would look like ("Practical oral," 2014).
