Ask HN: Survival guides in the wild

hello, can you please share with us if you have any good recommendation for a course/book/guide/compendium on survival guide in the wild? I am aware that in the end you have to go out and try it out for real, but before doing that step, what I am looking for is a compendium/book/course which is gathering together survival in the wild lessons, principles, rules, practices.

thank you
