Creating a works cited entry for an anthology is basically like a cross between an entry for a book and an entry for an article in a periodical.
First we list the author's name and the title of the selection. Then, we list the title of the anthology and the name of the editor. Finally, we list the publication location, company, year, page numbers on which the selection appears, and the medium of publication.
So, as an example, such an entry would look as follows:
Swanson, Gunnar. "Graphic Design Education as a Liberal Art: Design and Knowledge in the University and The 'Real World.'" The Education of a Graphic Designer. Ed. Steven Heller. New York: Allworth Press, 1998. 13-24. Print.
You'll have to locate the appropriate information within your anthology and follow this same pattern.
