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.
Making a Works Cited page is no longer difficult, thanks to the Internet. To find the latest up-to-date MLA format for citing literary works from anthologies, you can simply type in MLA in a search engine, and listings for how to cite whatever you have are given.
In your case, you want to look under Selection in an Edited Collection or Anthologies and you will be directed to list the editors, publishing house, date of publication etc. The entry should look something like this example, but you must indent the second and following lines 5 spaces:
Feist, Raymond E. "The Wood Boy." Legends: Short Novels by the Masters of Modern Fantasy. Ed. [this is the abbreviation for editor] Robert Silverberg. New York: Tor Books, 1998. 176-211.
In addition, there are other sites that will do the citation for you if you just submit the appropriate information. One such site is listed below.
