A citation is a reference to a source (author, book, article, etc.) from which a direct quote or information was taken that includes enough information to locate the original source. A book citation would include: author, title, place of publication, publisher, and date of publication. An article citation would include author, title, name of periodical, date, and page reference. Citations may be found in a research paper, a periodical index or in a catalog.  A compilation of citations is usually called references, works cited, bibliographies or endnotes depending on the style guide (APA, MLA, Chicago, etc.).
