For your report, I might have you borrow that Spofford book now. She works a lot with insanity and altered states of mind, so it could provide an interesting primary source of such things in literature of the time.

Meanwhile, Gilf and Taya. They're the only two I feel have been developed enough to really warrent enough connection with. Unless you want to be a brat and surprise me with some random slash instead. I'd accept that, I think. :P hehe.
