For what it's worth, Wal-Mart's online store (not the brick-and-mortar ones) carries the compact version for, like, $8 or $9, shipped. GREAT size. I keep one in each car, for that reason. A few of the diagrams didn't make it across in the modification from the full-size version, so you'll find yourself looking at text that references a diagram that's not there--but it's still a good book, at that size and price. Also, I know he could have done a lot better on the poisonous/edible plants of the Sonoran Desert stuff. I wouldn't be at all bothered had he just omitted them and said "get local instruction on edible and dangerous plants of your area," but, since he did decide to try to cover the topic, I figure I'll mention that that is a weak area, from what I know. But, overall, I'd give the book a 4 out of 5.
