Reddit mentions of Camp: Queer Aesthetics and the Performing Subject--A Reader (Triangulations: Lesbian/Gay/Queer Theater/Drama/Performance)

Oooooh, child, there is a lot of great stuff out there for you. Don't worry about not finding material.

• First of... "class just started"?? ew, are you doing a Maymester?! I will pray to the Drag goddesses for you.
  
  
• Second. How do you see the structure of the paper panning out? How are you using the documentaries? Because it seems like you could do a paper on depictions of drag (as fashion elements) in film alone and that already might make for an interesting paper. And that way you could also look at non-documentary works... Priscilla Queen of the Desert, La Cage aux folles, John Waters' early movies, Ma Vie en Rose, Hedwig, and Bad Education are all wonderful films. And plenty have been studied academically and have that kind of ~intellectual~ prestige that teachers love.
  
  
• I think "Notes on Camp" is good, but Sontag's text is pretty introductory, and a lot of scholars have built up (and taken down sometimes) on what she's said. I wrote a paper last semester on Pierre et Gilles for a class on contemporary art, and my most useful book was Camp, Queer Aesthetics, and the Performing Subject: A Reader. It's sort of this big encyclopedic book on past and contemporary scholarship on camp theory. There's a lot of great stuff on there, and I'm sure you could mine their bibliographies and expand your research that way.
  
• The other ~canonical~ text on drag is probably Judith Butler's Gender Trouble
  
• My other favorite (contemporary) book on drag is Jose Esteban Muñoz' Disidentifications: Queers of Color and the Performance of Politics
  He looks at drag from a cultural/ethnic perspective. Great read. Not all chapters would be applicable to your paper, as his scope is much larger than drag (as is Butler's), but he does devote a significant portion of his writing to Vaginal Davis.
  
  Let me know if you have any questions! I love this stuff. Good luck on your paper!
