There are piles upon piles of survivalist books. I'd rather they were slightly less of a thing though, because most seem to be by and for people who
want a total collapse and would probably prefer if we never rebuilt the present technological society.
I suspect the biggest technical problem with rebuilding would be chip fabs and other ultra high tech things, but the social problem would be bigger. I don't know what the social problem would be, but it would obviously be really big if civilization just collapsed.
Making pencils shouldn't be a problem if there's enough of a society left to find any graphite, all you need is a friend of a friend with a history book in the basement that says how they were made.
The other issue is any unlearnable/unteachable steps. There are millions of devices I could confidently use having never seen before, if I could study them with youtube vids.
Pre-tech era methods were full of things that were not fully technique based and relied on skills that can't be described. I could never paint a realistic face even if I had five years to study every book on technique available, and people used to do everyday things with processes like that.
Maybe it would be worth looking at historical processes, like how rope was made and such, and adapting them to be executable with pure book learning and basic tools, instead of "You have to keep just the right tension here and this should look about like that and...".
But I'm more interested in how we can prevent collapses entirely, and what we'd need to stockpile to be able to rebuild and continue, and who might try to interfere with that.
