The Boy Scout handbook would be a decent tool for basic camping skills, but of little value beyond that. If you are new to camping or the outdoors, then it will prbably have some useful information in it, but it will be crowded in with other stuff they deem important to the welfare of a young man.
A better book would be the Boy Scout Fieldbook. This one focuses on fieldcraft a bit more, with topics ranging from making your own mukluks from open cell foam and canvas to basic first aid, weather, backpacking and building fires. If you are a tech-geek, they tend to run a few years behind at the minimum, but they do teach pretty good fundamentals. Another good source, if you are looking for more specific information, is the merit badge pamhplets. These tend to be pretty specific in the requirements they cover, and these requirements may or may not include what you want to learn about, but they provide a step up from either book, in a specific topic.
Remember though, the Boy Scout's idea behind merit badges, and the rest of the skills they teach, is to provide a basic knowledge, and an introduction into a field, and then let the boy pursue further those things he likes. The Wilderness Survival merit badge does not require you to live off the woods for three weeks, but merely to show basic skills and knowledge that may enable you to do so if you want. Little is covered in it that has not already had it's own topic on this forum, and been discussed here for a week. The only thing it has which has not shown up here in as much depth, is signalling. But most of ya'll seem to be more focused on going out there and staying, or at least not desiring a helicopter to come pick you up...
Stryver, who likes the idea of a helicopter ride, until it's him or one of his charges who requires a ride...
