There are quite a few ways to cite resources in your paper. The citation style usually depends on the academic discipline involved.
APA (American Psychological Association) often used by Education and Psychology
MLA (Modern Language Association) typically used by the Humanities
Chicago Style (University of Chicago Press) generally used by History, Business, and some of the Fine Arts
CSE Quick Citation Guide used by Council of Science Editors, formally called the CBE Council of Biology Editors
Check with your instructor to make sure that you are using the appropriate style. And whatever style you choose, be consistent!
