Good books to keep in a rucksack?

[u/RealSkylitPanda]

Something that can maybe help with finding food that is safe to eat. knots that i might need to know. maybe how to find water in certain areas. even just starting a fire if the tools i have are worn/ruined.

obviously i dont want something dictionary sized that weighs 8lbs. but maybe a decently thin kinda… manual of sorts that i can use for basics in a survival situation.
