How To Cite These Web Pages
Every so often, I'm asked how these web pages should be cited. There's no one answer. Opinion and style vary according to whom you ask. The Bedford/St. Martin's web site has a comprehensive web page that presents style guidelines from MLA, APA, University of Chicago, and others, including a set of links to related web pages.
If the Bedford/St. Martin's page were to become unavailable, I recommend using a search engine such as Google to search on "citing web pages" or "citing web sources", with or without quotation marks.
