What other quite ‘fundamental’ info of that kind is out there?
You’ll have to specify “fundamental” better. What are you looking for? How to stop bleeding? How to start a fire in the rain? How to build a house with no tools other than an axe? How to run a farm with no engines or fertilizer?
In the US at least there is a large community/meme/circle of “survivalists” who are preparing for life after TEOTWAWKI—The End Of The World As We Know It. They have active forums and LOTS of information about what to do after a catastrophe.
See my edit. I know of that community as I read about them in a mixture of social and practical fascination. I ordered the info material mentioned because I was curious what my government specifically advises to do in different scenarios they deem plausible and they range from ‘simple’ house fires to large-scale contamination of air by biological or nuclear material.
