A works cited, bibliography, or references page is just a list of all the sources you cite (i.e. quote or paraphrase) in the body of your paper.
A great resource to start with is the NWTC Library Citation Guide.
You can click on APA, MLA, AMA, ACS and Chicago/Turabian tabs on the left side of the screen for detailed information on citing in those formats.
In the Citation Quick Links box, there are links to additional helpful APA, MLA and AMA resources.
