Here's a slightly different sort of book recommendation. It won't make you into a great animator, there are no images - at all, it's not written by an animator, it's not about animators specifically - but it is a great story about a company I'm pretty sure you've heard of. "To Pixar and Beyond" gives you a full insight into how Pixar came about and how close things were at times. It also paints Steve Jobs in a pretty good light!
