Ultra Light Backpackin' Tips, by Mike Clelland

This is good read if you are new to "Ultra-light" backpacking. It even has some helpful nuggets for experienced backpackers. While the writing is a little "cutesy", it probably makes the world of backpacking gear and spreadsheets palatable to the masses! The 153 tips inside are a valuable resource. I already figured I was an obsessive gear trimmer, but after reading this book I realized there were people even crazier than me. If you have never thought about trimming down your load, you absolutely should read this book. It will open your eyes, and get you thinking. Trust me, a lighter pack is a good thing. You will hike farther, and be in better shape when you get to the end.  End the suffering!  Get it here.
