For your final essay, please make sure to properly cite Monster Theory, by Jeffrey Jerome Cohen. Here is the information: In the parenthetical citation, simply use his last name (Cohen). You do not need to include the page numbers, since you don't have those. For the Works Cited page, here is the info to plug in:

Cohen, Jeffrey Jerome. Monster Theory. Minneapolis, Minnesota: University of Minnesota Press, 1996. 

Lastly, please note that the works cited page citation above is not formatted with the proper indentation (I can't do that in blogger), so make sure you indent the second line.
