This week is the 30th annual Banned Books Week, which was started in 1982 in response to the large number of books that were being challenged in schools and libraries. Efforts to ban books have resulted in a number of lawsuits challenging books ranging from the Bible to Slaughterhouse Five and everything in between. For more information, check out the map below, which highlights recent book challenges from across the United States.
