Some useful resources (most of this has already been mentioned):
winningonlinepoker.com
Steve Badger's Website
Annie Duke's Site on UltimateBet
Ray Zee's Book

The thing is, though, that while Ray Zee's book was good, after reading the information from the three aformentioned sites and having a fair amount of experience, I didn't really get much out of his book. It pretty much just echoed what I learned, maybe with a bit more description. To be honest, though, after just reading winningonlinepoker and playing a lot, most books I read have been a little disappointing. Even the books that are well done have thus far provided me with little more than echoes of what I already know... When people inform me that they're worth their weight in gold I just don't agree. Maybe it's because any "secrets" in them quickly become common knowledge to pretty much anyone ..
