There’s a book I found called “The Knowledge” that looks very useful. It doesn’t have many blueprints, but it gives enough understanding of the basics of how things work, that it could take a small group of people from the stone age to the mid-1940s level of technology, within a single generation.
I found it fascinating enough to read for fun.
I’m making a note of that. I have a couple of back to basic type books that describe early 20th century ways from back when everyone had gardens and some farms had water power and windmills etc.
I have one booklet called bicycle power or some such. All interesting, and potentially useful if an unfortunate event should happen, or maybe even a hobby should I ever have spare time. LOL
