A citation reflects all of the information a person would need to locate a particular source. For example, basic citation information for a book consists of name(s) of author(s) or editor(s), title of book, name of publisher, place of publication, and most recent copyright date.
A citation style dictates the information necessary for a citation and how the information is ordered, as well as punctuation and other formatting.
A bibliography lists citations for all of the relevant resources a person consulted during his or her research.
In an annotated bibliography, each citation is followed by a brief note—or annotation—that describes and/or evaluates the source and the information found in it.
A works cited list presents citations for those sources referenced in a particular paper, presentation, or other composition.
An in-text citation consists of just enough information to correspond to a source's full citation in a Works Cited list. In-text citations often require a page number (or numbers) showing exactly where relevant information was found in the original source.
