What's the difference between APA and MLA citation styles?

Answer

For more information, checkout our Citations Guide

Both styles give rules for citing sources, but different academic disciplines use them.

APA (American Psychological Association)

  • Psychology
  • Nursing, Business, and some social sciences are adopting it.

MLA (Modern Language Association)

  • Literature; Languages
  • Most of PCC's Writing courses.

 

Differences: In-text citations & the list of references (or works).

APA style

Garcia (2018) found that language on Twitter is evolving, due to pressure to be both concise and

emotional. However, a later study saw no such evolution (Armstrong, 2020).
