Query: Golden age of American studio animation

I am not an animation student, merely an ardent fan with many years of armchair learning to my credit. My copy of this book is now nearly 20 years out of date and the softcover spine is wrecked beyond repair, but I still frequently refer to Maltin's incomparable history of the subject, by studio, and to the exhaustive filmographies in the back. No matter what turns up on Cartoon Network from the classic age, I'm ready for it, with insight and clear, impassioned writing on the subject. It isn't for nothing that this book has become a standard in classrooms.
