Why does it even matter if there are books that aren't in the school library? It's not like there's no way a student could read a certain book just because it's not inside the school. This is as pointless as arguing about which restrooms people can use. People on both sides get all worked up and upset, but at the end of the day a student can read a book even if it's not in the school and anyone can use any restroom. My mom used to go in the men's room all the time and nobody ever took any issue with it. I've read tons of books that weren't in my school library. In fact, almost every book I've ever read wasn't in my school library.
