that’s an awfully broad question to answer without knowing something about your knowledge base and experience.
i’ve got a bookcase that’s mostly survival and prep related books. from military field manuals, to the Foxfire series, to Carla Emery’s book, books on knots, “Where there is no doctor”, etc. i think i still have some of those books in boxes from when i moved (along with all the fiction books).
do you want info on farming and animal husbandry? first aid? primitive camping? plumbing? alternative energy? canning? small motors? building sheds and small cabins?
the problem i’ve seen with some of the general books is that they don’t go into enough detail on specific subjects.
some have simply been interesting to read, some have been so bad that i skimmed thru them and but them back on the table or shelf. Duncan Long’s gun books were really bad IMHO. his book on the AR was so bad it was scary.
are you the handyman around the house or do you call the plumber or electrician for any problems? do you wrench on your own vehicles, or take it to the dealership? do you own your own home or rent an apartment?
i’m not concerned with where you are and what you know now… as long as you have the ability to learn. many people don’t. that’s not directed at anyone, that’s just a general statement. i’m always trying to learn new things and wrench on vehicles, do basic electrical wiring, plumbing, and other home improvement stuff. i’ve got a single family home on a small suburban lot. i’d love to have many acres someplace further out of town, but that’s not happening with my current budget.
some people are like a sponge and soak up any knowledge they come across, other people are like… err, well some colorful images come to mind but let’s just say that they don’t seem to learn anything new. if you’re here and asking i’ll have to assume you’re not one of those types.
but the problem is that there are so many options it’s a hard question to answer.
