A new book titled Charles Addams — A Cartoonist’s Life is out. There's a review from a Nashville paper here. It's short. Actually, the Amazon site has a better descrip.
This is the first bio of Addams, one of the most important New Yorker cartoonists. He certaily had a major impact on a lot of other cartoonists. The book has unpublished photos and drawings. I haven't seen it in the bookstores yet, but it sure looks like fun.
