There are plenty of busybodies running the school libraries ensuring books people would read never get bought and purging collections of books now deemed heretical.

There are plenty of busybodies lobbying bookstores to stop selling books.

These books don't, or rarely, make banned book lists. It's done quietly out and out of the public view. The books that get shilled as 'banned books' are all largely (not wholly) books agreeable to a particular class of people.

For example, a very popular children's author who passed away some time ago is completely banned from my library system for ideological reasons.
