Tutorials/Books for Illy

What are the best places or books to read up on Illustrator. I been working with photoshop mostly and wanted to learn Illustrator better.

there's some beginner stuff you can find right here
It's not much yet...but stay tuned hihi. Illustrator WOW is a great book. and you can always check the knowledge base at adobe..

Ok thanks for the suggestion about the book. I know the basics of illy, but wanted to get at it like I have with photoshop over the years :D Thanks again!
