bibliographies: types of bibliography

Various types of bibliography are possible, depending on the nature of the book or document in which they are to appear.

A bibliography may list all the works consulted by a writer, as well as others the writer believes readers will find useful; or it may be restricted to a listing of works actually cited in the text.

An annotated bibliography contains comments made by the author concerning the scope, usefulness or other features of the works listed.

A bibliography may appear at the end of a book, report or other document (before the index, if any), at the end of a chapter, or as a separate document.
