Banned Books Week 2010 runs from September 25th to October 2nd. It is sponsored by the American Booksellers Association, the American Booksellers Foundation for Free Expression, the American Library Association, the Association of American Publishers, the American Society of Journalists and Authors, and the National Association of College Stores. The annual stand against censorship is also endorsed by the Library of Congress Center for the Book.

The ALA Office of Intellectual Freedom compiles an annual list of the “Top Ten Most Frequently Challenged Books.” The 2009 list, available here, includes the Twilight Series, along with older favorites such as J.D. Salinger’s Catcher in the Rye, Alice Walker’s The Color Purple, and Harper Lee’s To Kill a Mockingbird, which was published in July 1960.
