In honor of National Library Week, the American Library Association has unveiled the 10 Most Challenged Books of 2012.

The Most Challenged Books are as follows:

1) Captain Underpants (series) by Dav Pilkey
2) The Absolutely True Diary of a Part-Time Indian by Sherman Alexie
3) Thirteen Reasons Why by Jay Asher
4) Fifty Shades of Grey by E.L. James
5) And Tango Makes Three by Peter Parnell and Justin Richardson
6) The Kite Runner by Khaled Hosseini
7) Looking For Alaska by John Green
8) Scary Stories (series) by Alvin Schwartz
9) The Glass Castle by Jeanette Walls
10) Beloved by Toni Morrison

According to the ALA, a book receiving a challenge is defined as “a formal, written complaint filed with a library or school requesting that a book or other material be restricted or removed because of its content or appropriateness. In 2012, OIF received 464 reports on attempts to remove or restrict materials from school curricula and library bookshelves. This is an increase from 2011 totals, which stood at 326 attempts.”

John Green’s Looking For Alaska has been under fire for many years because of the book’s sexual content. The fact that it made the list again this year may suggest it’s still being put on school reading lists.

No one will be surprised to see that Fifty Shades of Grey, which is essentially Twilight mommy porn, appeared on the list. The book was the best selling book of 2012.

Congratulations to all of the Most Challenged Books! Banned Books Week is held every year in October.
