The OWL(Online Writing Lab) at Purdue is a very highly regarded source of help for student writers. They have guides to all the main citation styles. You can see how to cite all different types of sources and also get help formatting your paper for those different styles. For this course, you should use either MLA or Chicago (using footnotes).
You can also access the complete, official online version of the Chicago Manual of Style as well as its own quick online guide to formats using the links below. If you are not on campus, you will have to login using your SCU credentials to access the full version of the online manual.
