Searching in the Gender Studies Database (possibly available at your college), I found a reference to the following book: Blending Genders: Social Aspects of Cross-Dressing and Sex-Changing (1996). It contains the "Gender Fucking or Fucking Gender?" essay mentioned in the answer above.

If you're interested in less scholarly uses of the term/concept, you could try searching in Google Groups, a search that includes Usenet postings going back to the 1990s.
