Beginning with the Op-Ed, your essays will have to include a Works Cited. Please understand this is different from a Bibliography, which identifies every source you consulted in your research. The Works Cited identifies only (this will sound so obvious!) works cited in this particular essay.
If you get your sources through the library databases, you can use Prof Search or RefWorks to produce automated Works Cited citations. A little experience with RefWorks will also accustom you to the mechanics of common citation types. But if you get stuck for a particular style, the Online Writing Lab (OWL) at Purdue offers a free online guide to citation.
A link to the OWL material is always available in the Resources section of the sidebar.
