A bibliography is an alphabetical listing of the sources you used in writing your paper. Your bibliography must include all the sources that appear in your footnotes or endnotes. However, do not include all of the sources you looked at in the course of your research. If your bibliography is a long one (say, more than twenty items), you should separate it into categories such as primary sources, books, articles, newspapers, magazines, and nonprinted sources such as tables, illustrations, and Web pages.

• A bibliography is alphabetized according to the last name of the author.
• If a work has no author (or editor, or translator), alphabetize it according to the first word (except for A, An, and The) of the title.
• Begin each bibliographic entry at the left-hand margin, and indent any additional lines five spaces.
• Each item in a bibliography is single-spaced with double-spacing between items.
• The form used for writing a bibliographical item is different from the form used for writing a footnote or an endnote. For footnote and endnote form, see How to Write a Footnote or an Endnote for a Book.
• For example, in a bibliography the author's last name comes first. For other differences, see the next screen.
