The Hobbit is banned by multiple school districts. It actually pissed off a lot of teachers too. It is books like that being banned that make teachers not want to have a library at all. It is really easy to have a banned book, and teachers do not have the time to source each book in their already existing libraries.
But I guess in their words:

Wow! I'd no idea the Hobbit was banned anywhere. Madness. Its just a work of art. Hardly even controversial. Kids should be able to make their on judgement about it. People need to be allowed to think critically. I could possibly see why one might disallow, say, Mein Kampf in a school library but even then you could possibly have, for historical purposes, a copy annotated with a lot of warnings and reminders of who the author was and what he did.
