Yes. Obviously there are books that are inappropriate in elementary school libraries. Different criteria may apply to high-school libraries. But the point is these are curated collections no matter what. Nobody is prevented from reading what they want to read outside of that.

My high school library didn't offer much popular paperback fiction, but I could have found that at the county public library, or at any bookstore or most general retail stores.

School libraries have limited space, funds, and are constantly making decisions about what is age-appropriate and of educational value.
