Yep I agree, the first Beyond Brawn was so comprehensive it covered every aspect of weight training (nutrition to a lesser extent though), that any further books would not really be able to add a hell of a lot more.
He did a second one that included a complete program for newbs, laid out over several months, but I wasn't a fan of his suggested program (too many exercises and sets in a single workout). Most other aspects of his material I generally love.
