A bibliography is a list of sources about a single topic. Each book listed in the bibliography is identified by its Author, Title, Publisher, Place of Publication, and Date of Publication. Articles from newspapers, journals and magazines include the title of articles, the authors, the journal or magazine, where it was published and the Volume, Issue Number, the Date of the Publication and the Pages the article appeared on. Each discipline has its own style for creating bibliography entries, e.g. MLA, APA.
