If you're serious about becoming an animator in any style from traditional hand drawn animation to 3D computer generated animation and everything in between (even cut out or stop motion... brickmation even) this book is a must have. Not just on your book shelf but well within reach of your work space. The Animator's Survival Kit, Expanded Edition by Richard Williams is considered to be the animator's 'bible' for good reason. It's simply the best book on the craft of animating I've ever read (and if you're a regular reader of this blog you'll know I've read a few).
