To Kill a Mockingbird. The Great Gatsby. The Diary of Anne Frank. Where the Wild Things Are. These aren’t just beloved, classic books — they’re books that have been banned or challenged over the years. Now, the American Library Association has released its list of 2014’s most-challenged books.

The list was released by the Association’s Office for Intellectual Freedom, which conducts oversight on library professionals and collects statistics on censorship. It uses newspapers and individual reports of challenges to published materials, then publishes a bimonthly newsletter on challenged books and compiles the statistics into an annual list. Every year during Banned Books Week, the list is published in what the Association calls an effort to “inform the public about censorship efforts that affect libraries and schools.”

This year, the ALA reported 311 formal, written challenges to books. At the top of this year’s list is Sherman Alexie’s The Absolutely True Diary of a Part-Time Indian, which was number three on last year’s list. Dav Pilkev’s Captain Underpants series, which topped last year’s list, has fallen off the list, though Pilkev still remains on the ALA’s list of frequently-challenged authors.

In an infographic about challenged books, the ALA notes that 35 percent of challenges come from parents and 38 percent are filed in public libraries. Over the last decade, notes the ALA, over 5,000 challenges have been recorded by its Office for Intellectual Freedom, 1,577 of which were for “sexually explicit” material and 1,291 of which were for “offensive language” (age inappropriateness, violence and homosexuality also top the list of reasons why people challenge books).
