Pamela Paul, former editor of NY Times Review of Books, writes in the NYT: There's More Than One Way to Ban a Book
Though the publishing industry would never condone book banning, a subtler form of repression is taking place in the literary world, restricting intellectual and artistic expression from behind closed doors, and often defending these restrictions with thoughtful-sounding rationales.
John Sexton talks about it in this Hot Air post: The far left bans books by not letting them get published in the first place
I've written a couple posts on this that went unpublished because I wasn't happy with how my point was coming across. Sexton nailed my point much better.
That basically is: Parents, schools and administrators deciding what is or isn't age-appropriate reading in their schools, is NOT banning books. It's called setting curriculum. There is actual banning of books or authors by book publishers, stores and nations around the world, but if a public library or local bookstore can do a display of "Banned Books" to lend or sell, then they aren't banned books.
