In most social science classes, you will be asked to use the APA (American Psychological Association) system for documenting your sources. APA recommends in-text citations that refer readers to a list of references.
The APA Guidelines resource, created by the Meramec Campus Writing Center, provides many useful examples demonstrating how to cite a wide variety of sources.
The Purdue Online Writing Lab (OWL) will also help you learn how to use APA. The APA section of OWL contains information on in-text citations and the References page, as well as APA sample papers and slide presentations.
