“There are hundreds of challenges to books in schools and libraries in the United States every year. According to the American Library Association (ALA), there were at least 513 in 2008. But the total is far larger. 70 to 80 percent are never reported.”

I found this back during Banned Books Week and neglected to post it then. It’s a map of banned or challenged books in the US.

Overlay this with the traditional Red/Blue map, and there are a few surprises.
