True, angry people rarely gather in the town square any more for a book burning, but that doesn't mean campaigns to ban books have ended.
To mark National Library Week, the American Library Association put out its list of 2013's "most challenged" books; that is, books people vigorously campaigned to ban from libraries, schools and other places because they take offense to something in the text.
While some of the subject matter is indeed heavy -- teen suicide, dystopian games of murder, erotica -- you might be surprised at some of the contenders for most challenged books.
The books are:
1. The Captain Underpants series, by Dav Pikey
Two fourth-graders' imaginary comic book hero, Captain Underpants, comes to life and apparently real-life parents freak out over visible underwear and children being disobedient.
2. "The Bluest Eye," by Toni Morrison

7. "The Perks of Being a Wallflower," by Stephen Chobsky
