A citation is the information that is used to help a reader, usually your professor, identify and locate an information source that is referred to in a paper or presentation. When you write a paper, you cite your sources in a bibliography or works cited list. This list of references helps you back up your opinions and adds credibility to your presentation and helps others find those sources and come to the same conclusions.
Various style guides call for slightly different citation layouts, but the same basic elements are usually used. This course will focus on the MLA documentation style, but you may use others, such as APA or Chicago style in other classes.
