New Erlang book

There is a new Erlang book coming out soon, Programming Erlang: Software for a Concurrent World by Joe Armstrong, which is very good and a great improvement over the old book. Apart from a very understandable description of the language it all also describes some of the more generally useful libraries, and gives real-world examples of how to use them. As I already know the language it is the second part of the book which I find most helpful.

In all the book is well worth reading.
