I've been looking around for good survival/bushcraft books and guides (for general and fundamental knowledge and techniques, I'm quite a newbie with this stuff) and I've seen a lot of conflicting takes. However, I've noticed that most people say survival guides and books aren't all that good and that the military has better literature on the subject. My question is simply what should I look for in these books to know that they aren't giving bogus information? (any personal recommendations are also welcome).
Specifically, what I'd like to prep for is something like a hiking trip, (what kind of wood is good for fire, first aid dos and don'ts, etc.)
