What do classics like "The Chocolate War," "To Kill A Mockingbird" and "Catcher in the Rye" share in common?
They're on the list of the most challenged books at libraries and schools.
These time-tested works are included in the top 10 list of the most frequently challenged books of last year, compiled by the American Library Association's Office of Intellectual Freedom (OiF).
This year Lauren Myracle's best-selling young adult novel series "ttyl," tops the list. That book is the first-ever novel series written entirely in instant messaging style.
A challenge is defined by the OiF as a "formal, written complaint, filed by either a library or school, requesting that the books be removed or restricted because of content." The OiF received 466 requests to remove or restrict books in 2009.
It estimates that this number reflects only 20-25% of the challenges actually made at public libraries, school's and school libraries.
