This is the canonical guide and is also good read for those of us whose PC tours are in the future. One thing I thought I'd mention is that the (needed) fourth edition has just come out. So far I have only seen it at the online
Mountaineers Books shop. Worth ordering it from them until it appears at the other shops. Beware of places ditching the old versions.
on edit:
Actually looks like this is now at Amazon (wasn't as of last week)
