A bibliography is a list of sources that have been used or referred to in a written work, such as a book, article, or research paper. It typically includes bibliographic information about each source, such as the author, title, publisher, and date of publication. The purpose of a bibliography is to provide a list of references or citations for the sources used in the work, so that readers can find more information about the topics discussed and the ideas presented.
Bibliographies can be organized in a variety of ways, such as alphabetically by author, chronologically by date of publication, or by the type of source. They may also be formatted according to specific citation styles, such as MLA, APA, or Chicago, which provide guidelines for how to organize and present the bibliographic information.
