I own this one, as well as Dartnell’s The Knowledge: How to Rebuild Our World from Scratch because I am a massive tech history nerd. (I’d love the idea of being able to survive a collapse but I’m too self-aware of my insufficient physical fitness for that, lol.)
Also for those who’ve not heard of the BBC series Connections, it’s AWESOME. More useful for entertainment than as a reference, but the first episode literally explores the question “what would a single human have to do to survive if modern life suddenly became unavailable?” Here are all the episodes on Archive.org.
