+1 for the Java Concurrency in Practice book. It's the book I recommend to nearly everyone who wants to get into concurrent programming. Goetz makes it a lot more approachable than most other books.
Goetz has come a long way. I knew one of the people who contributed to that book and he was a little frustrated about having to explain things to him he felt he shouldn’t have had to. The implication was he’d already had this conversation with some of the other contributors.
Sometimes though, the newbie is going to write the clearest documentation.
