Manning has a draft PDF available of a new Erlang book, with an emphasis on OTP, the platform/framework/library/what-cha-ma-call-it that helps in the development of robust, concurrent, distributed systems. I bought it, yes, I did. Co-authored by Martin Logan - no relation that I know of, and no damn discount on the book either!! (Well, I didn't ask. :-)
There are only a couple of draft chapters currently in the draft. But this should be a good addition to the growing supply of help getting going with Erlang.
I think the Seaside folks have made this "the year of Smalltalk" but there's an argument to be made for this being "the year of Erlang" as well.
