My college roommate was fond of saying that every good relationship starts with a one-night stand. OK, so he was an idiot, but what is true is that every good mountaineering trip starts with glacier travel.
There are just a handful of books out there on the topic and the acknowledged classic is Andy Selters' Glacier Travel & Crevasse Rescue. It's out in a "revised" 2006 second edition, which is now part of the Mountaineers Outdoor Expert series and adds just a few new tidbits of information (to the previous 1999-2004 printings of the second edition) like the butterfly knot and the harness-ax belay.
The other two books I like to flog are Glaciers! from Falcon's How to Climb series and Glacier Mountaineering from Climbing Magazine. The latter has Mike Clelland's excellent illustrations; his books with Andy Tyson are all worth owning. If you're out there playing crevasse roulette you really should buy and read all three.
