Looking on Amazon and other sites the cheapest paperback is $116. Why?? I understand this book is kind of a cult classic but are there only a limited number of them?

I actually had P.F. Kluge as my professor in college and have read (I think) 3 of his other books. Should’ve asked him for a copy of this one lol.

Just wondering what the reason for this is, and if I’d actually be hard pressed to find a copy at a bookstore/Barnes and Noble
