You must cite the sources you use in your academic work. Sources are cited both within your text and at the end of the paper, in a list called a bibliography, works cited, or references page. MLA, Chicago, and APA styles are frequently used in university-level academic work. Each of these styles is explained in a manual, with instructions for formatting citations to different kinds of sources.
The print editions of the leading style guides are considered the authoritative source. Easy Writer summarizes the major styles and will answer most questions on citing. Print style manuals and a copy of Easy Writer are available at the library service desks or for purchase in the campus bookstore.
