Since the MLA, in its infinite wisdom, has decided that the URL no longer needs to be included in a Works Cited page, I've updated the citation formats on the Literary Movements pages as follows:
To cite this page on a Works Cited page according to current MLA guidelines, supply the correct dates and use the suggested format below. If you are quoting another author quoted on this page, either look up the original source or indicate that original quotation is cited on ("Qtd. in") this page. The following is drawn from the examples and guidelines in the MLA Handbook for Writers of Research Papers, 7th ed. (2009), section 5.6.2.
Campbell, Donna M. "Page Title." Literary Movements. Dept. of English, Washington State University. Date of publication or most recent update (listed above as the "last modified" date; you don't need to indicate the time). Web. Date you accessed the page.
The information is found on p. 186 of the new MLA Handbook.
