Hmmm, maybe that's a big reason for the bookstore closures. As an academic, and a generally all-round weird person, I have eclectic reading needs. I don't see any reason to pay full price for anything, including books. Much of what I want to add to my library is available used on Amazon. What I want to just read, but not keep, I get from my university library. Whle not everyone has access to a huge university library, almost anyone can buy used off of the net.
