Citations, in the research world, have nothing to do with traffic tickets. Instead, citations identify published information in order to locate that item again. Citations of articles often include the author, title, magazine or journal name, page numbers and publication information. Citations of Web documents also include a URL and the day the information was accessed.
The list of the sources you used when researching your paper is called a bibliography. These sources are listed in citation format and follow an established style, such as MLA (Modern Language Association), APA (American Psychological Association) or Chicago Manual of Style. The bibliography allows others who read your work to verify facts or research the same information more easily.
