Magento books/tutorials?

Hey, can anyone recommend some good resources to learn Magento?

I prefer books to web tutorials, but either one works. I know HTML , CSS, Javascript, PHP etc all pretty well.

Magento website and forums is a good start. They also have a book: Magento User Guide

Look at packtpub for books

Here it is: http://www.packtpub.com/magento-1-3-theme-design/book
