APA tip: In-text citations

by Barbie in APA Style

When you refer to authors within the body of your paper, you place only the year in parenthesis. Many of our clients add a comma after the closed parenthesis, but that is not always necessary. APA does not recommend using this comma, unless the structure of the sentence calls for a comma there. Here are some examples:

Standard APA format

  • Peterson and Williams (2009) explain that some individuals use a comma too frequently.

Sentence structure where a comma is warranted

  • According to Johnson and Miller (2013), students use commas after introductory phrases.
