I just picked up a new book by Field & Stream, its really cool.
"The Total Outdoorsman Manual - 374 Skills you need"
It has 4 sections (Camping, Fishing, Hunting, Survival).
It has tons of pictures, diagrams, for the randomest and craziest situations you could come across. Tons of tips as well.
A few fishing tips include: How to carry a tacklebox around your neck, how to scale fish with bottle caps, etc.
