The Golden book of Camping and Camp Crafts is top of my list. National Audubon Society Field Guides to Insects and spiders, Reptiles, birds, trees. Those were my go to books to browse while eating lunch during summer vacation.
For fiction Julie of the Wolves by Jean Craighead George was my favorite. She does it right. Z for Zachariah by Robert C. O'Brien. Also Journey Outside by Mary Q. Steele. They are good because they make a point of the main characters survival skills both practical and mental.

Those are what come to mind right know. I'll probably remember others
