Query: Bryn Thomas' Trans-Siberian Handbook the way to go

You'll get more of the generic country information that LP is good at (and provides in their various country-specific guides) but we found the research in the Handbook provides a much more informative passage across the time-zones. By far the best and most up-to-date source of information on booking tickets is a website called "www.seat61.com". Having tried various "tour" organisations, we ended up booking all arrangements through one of the recommended Russian agencies for half the price - all through internet cafes on the hoof in Bolivia! As for companion guides, much preferred the handbook.
