Please note that the most frequently challenged authors may not appear in the list of most frequently challenged books. For example, if every one of Judy Blume’s books was challenged–but only once–not one of her books would make the top 10 list, but she herself would make the most challenged author list. Five of Judy Blume’s books are on the list of The 100 Most Frequently Challenged Books of 1990 to 1999: Forever (7), Blubber (30), Deenie (42), Are You There, God? It’s Me, Margaret (60), and Tiger Eyes (89).
