Quite frankly, I don't mind if the library at school is banning them. I think it is a parental thing to determine what books are appropriate and if the child wants to read a certain book and it is not available at the school, then ask their parents and surely mum or dad could take them to the local library or purchase the book if the child is that interested.

TBH I very rarely read books from my school library as they didn't appeal to me. My mum would take me to the local library at least once a fortnight to exchange the books I had checked out. It was a great mother/daughter experience as it always turned into a coffee/hot chocolate chat session.
