APA Style

The APA style manual (American Psychological Association) is most commonly used to cite sources within the social sciences. It refers to the rules and conventions established by the American Psychological Association for documenting sources used in a research paper. APA style requires both in-text citations and a reference list. For every in-text citation there should be a full citation in the reference list and vice versa.
