I've got both the bigger book and the small one. The little one goes in my day pack. The bigger one is just fun to look through or for bathroom reading. Well worth the money, even if everything in there is not entirely practical (constructing a sod house comes to mind). My wife looked over my shoulder one time when I was perusing the larger of the books. She said, "Oh good, you know how to trap a wild pig now. That might come in handy!" We still laugh about that comment to this day.
