I've tried Kent's excellent Google Advanced Search instructions to search on the Helpline for the best way to tear up my France guidebook (I only need about a third of it) without wrecking everything. Apparently, my search terms don't float Google's boat, but I KNOW someone at one time posted some really good proven methods for dismantling books. If anyone can either PM me and tell me how to do it, or just reply here and point me to a good thread, I would be grateful. Thanks!
UPDATE: I took my 900-page Rick Steves' France guidebook to Kinko's at lunch today. I asked them to shave off the binding, which they did. I then sat down at a nice workstation and pulled out the pages I wanted to keep, and I put them in the order I wanted, and then asked Kinko's to put a coil (spiral binding) on. It cost a mere $2.18, and I'm down to 70 pages! It will weigh virtually nothing in my bag, and I'm so pleased. Thanks for all your wonderful suggestions!
