APA Citation & Format (7th ed.)

Author-Date In-Text Citation

Use the author–date citation system to cite references in the text in APA Style. In this system, each work used in a paper has two parts: an in-text citation and a corresponding reference list entry.

In-text citations may be parenthetical or narrative.

  • In parenthetical citations, use an ampersand (&) between names for a work with two authors or before the last author when all names must be included to avoid ambiguity.
  • In narrative citations, always spell out the word “and.”

Number of Authors to Include in In-Text Citations

The format of the author element of the in-text citation changes depending on the number of authors and is abbreviated in some cases.

  • For a work with one or two authors, include the author name(s) in every citation.
  • For a work with three or more authors, include the name of only the first author plus “et al.” in every citation (even the first citation).

The following table shows the basic in-text citation styles:
