What is APA? What does APA style mean?

APA is a particular style or format (a set of rules, essentially) for structuring an essay or a research paper in the social and behavioral sciences. The style helps your professor see exactly where you found the research that you add to the paper and lays out exactly how the paper should look (margins, titles, page numbers, etc.).

The guide is a joint effort by CSN Libraries and the CSN Writing Center.
