This isn't clever or insightful. You can of course condense down critical information into a survival handbook, but in existential crises you don't necessarily know in advance what you'll need to know. Wikipedia (as a benchmark repository of knowledge) is ~5 million pages and would require a decent-size room to store if printed out. By contrast, a laptop + solar panel can fit in a backpack. SD cards/USB sticks with the capacity to store all of Wikipedia are a few $ each.
If things are so bad that you need to factor in the non-operability of any electronic devices, how many indestructible paper libraries are you planning to build and manage in advance, and at what budget?
The pedanticty (or is it pedanticness???) on hn is astonishing sometimes.
If there's any place to get an answer it's here.
Bravo my friend. And I mean that in a good way. Love me some diversity.
