"In short, he made it clear that the book was being challenged because of its politics and its content."

Cory Doctorow at boingboing:

My publisher, Tor Books, is sending 200 free copies of the paperback of my novel Little Brother to Booker T Washington High School, because it's the first school where any of my novels has been challenged by the school administration. Little Brother had been selected and approved as the school's summer One School/One Book reading pick, and the school librarian Betsy Woolley had worked with Mary Kate Griffith from the English department to develop an excellent educational supplement for the students to use to launch their critical discussions in the fall. The whole project had been signed off on by the school administration and it was ready to go out to the students when the principal intervened and ordered them to change the title.

So that's going on.
