What is APA style?

APA Style refers to citation guidelines developed by the American Psychological Association. APA is widely used in social sciences.

How does APA work?

The APA style uses an author-date system of citation. Brief citations in the text direct the reader to the corresponding entries in the reference list at the end of the paper.
