That is a great book. There are several out there that are really good to have or at least read through once, and many of them are focused on drawing, which is really the best way to learn to apply the principles of animation. Other good books: The Animator's Workbook - Tony White Cartoon Animation - Preston Blair How to Draw Animation - Christopher Hart There are countless references on the web too, although they tend to be much shorter and less detailed than what you find in a book. Do a google search for "principles of animation". http://www.cgnetworks.com/story_custom.php?story_id=1429&page= http://www.gamasutra.com/gdc2003/features/20030308/kane_01.htm
