The 2 oz. Backpacker

from the introduction:
Readers have asked for a featherweight source book they can justify carrying along with them in the wilds, something that will provide a backup to their own experience, help them deal with adversity and ensure getting the most from trips. I've tried to cram all the data I can into a small, tough, flexible format on light, thin but high quality paper, aiming for a total weight of 2 ounces so that weight-conscious backpackers will carry it. (If the printer failed to "make the weight" you can always rip off the covers or take scissors to the margins.) This isn't a survival booklet. A backpacker shouldn't need to know how to rub two sticks together for fire, flag down a passing plane, snare rabbits, or cook without pots. This is strictly a field guide. I have wasted no space on data that can't help you in the wilds. If you want to know how to choose the right gear, get in shape, travel light, select clothing, plan menus and trips, etc., get Pleasure Packing for the 80s. It's a soup to nuts, 255 page reference book on backpacking - but it weighs twelve ounces.
