Alright, I want to begin a serious study of Illustrator CS. I have the program and I've been taking a CG class at school and I'm familiar with raster-based programs such as Paint Shop Pro, a bit of Photoshop, and Painter. What are the best books, from starting up to advanced stuff, for learning it? I know the basic features and tools since that's what we're covering right now in my CG class, but I want to get familiar with it inside and outside. I prefer books for studying in-depth stuff, as opposed to websites (can't stand reading ebooks).
