For any research paper, you must cite the sources that you use within the text as you discuss them AND at the end of the paper in a bibliography commonly called a Works Cited or a References page. Universities most often use APA, MLA or Chicago style, and each style manual dictates how you should produce these citations, both in-text and in your bibliography.
MLA Style, or the Modern Language Association Style, is more often associated with the Humanities, for subjects such as literature, modern languages, cultural studies, and the fine arts. APA Style, or the American Psychological Association Style, is more often associated with the Social Sciences -- subjects like Psychology, Education, Business, and Political Science. Chicago Style actually has two different style options for citing and is used for a variety of subjects across disciplines.
