Regarding the controversial Charles Schulz biography…Schulz's son Monte summarizes the family's view of the book over in a comment on the Cartoon Brew website.
There's a website for the book that includes a video with the author, David Michaelis.
I already pointed you to a review by Bill Watterson. I should have also sent you to this review over on the Aaugh! blog, which is part of the best website on the 'net for Peanuts info. Plus, I should have pointed out a certain irony to the Watterson review. Here's a guy who has been fiercely private about his own life and he's applauding a book which delves deeply into Schulz's personal history.
In case you want to order the book, this link will get you one from Amazon.
