With most research projects, your instructor will ask you to cite the sources you used, i.e., to create a bibliography. There is more than one "right" way to do this. The most common methods of citing sources are the APA and MLA styles; be sure you find out from your instructor which one you need to use for each project. Here's a side-by-side comparison of how a simple citation for a book would look in both APA and MLA formats:

Creating entries for a bibliography means giving the basic information needed for someone else to quickly and accurately identify each source you used. The kinds of information needed varies from one kind of source to another. In the three pages on Finding Books, Finding Articles, and Finding Web Resources there are basic listings of the kinds of information you will need.

Sources can be very complex to deal with, however. For detailed information on citing sources, you will need to consult online sources or printed books for the appropriate kind of style you are required to use. InfoTree has a page with links to online style guides; you may also wish to consult a librarian for additional resources or for help at interpreting these guides.
