The American Library Association (ALA) has created this excellent resource for those seeking to learn about books that have been challenged around the United States. These lists have been compiled by the ALA's Office for Intellectual Freedom since 1990. Users can dive in by browsing the listings on the left-hand side of the page including Authors By Year, "Banned & Challenged Classics," and "30 Years of Liberating Literature." The last area is a great place to start as it features a profile of Banned Books Week where visitors can learn about books that have been banned in different communities including "And Tango Makes Three" and "The Giver." The Authors By Year section features a list of those authors whose works have been most frequently challenged since the ALA started compiling their lists. Another compelling section is the Statistics chart which offers a visual representation of the challenges by year, reason, initiator, and institution.
