The title is usually prominently displayed in the work, often near the author. If the title has a subtitle, include it after the main title.
Titles and subtitles are given in the entry in full exactly as they are found in the source, except that capitalization and punctuation are standardized.
A title is placed in quotation marks if the source is part of a larger work. A title is italicized (or underlined if italics are unavailable) if the source is self-contained independent.
For titles and subtitles, capitalize the first word, the last word, and all principal words, including those that follow hyphens in compound terms.
When an untitled poem is known by its first line or when a short untitled message is identified in the works cited list by its full text, reproduce the line exactly as it appears in the source.
Use a colon and a space to separate title and subtitle, unless the title ends in a question mark or exclamation point. Include other punctuation only if it is part of the title or subtitle.
A book is a whole unto itself. This means that the title is set in italics.
Here is an example:
Jacobs, Alan. The Pleasures of Reading in an Age of Distraction. Oxford UP, 2011.
A collection of essays, stories, or poems by various authors is also a whole unto itself. This means this title is also in italics.
Here is an example:
Baron, Sabrina Alcorn, et al., editors. Agent of Change: Print Culture Studies after Elizabeth L. Eisenstein. U of Massachusetts P / Center for the Book, Library of Congress, 2007.
An essay, story, or poem in a collection is part of a larger whole. This means the title should be placed in quotation marks.
Here is an example:
Dewar, James A., and Peng Hwa Ang. "The Cultural Consequences of Printing and the Internet." Agent of Change: Print Culture Studies after Elizabeth L. Eisenstein, edited by Sabrina Alcorn Baron et al., U of Massachusetts P / Center for the Book, Library of Congress, 2007, pp. 365-77.
BUT when a work that is normally independent (such as a novel or play) appears in a collection, the work's title remains in italics.
Here is an example:
Euripides. The Trojan Women. Ten Plays, translated by Paul Roche, New American Library, 1998, pp. 457-512.
