Catastrophe happens, What would happen to all of the world's knowledge?

Question

Let's say that for some reason or another, a catastrophic event happened where we had no more access to the internet, essential resources, and a good chunk of humanity was wiped out.What would to all of humanity's knowledge, how hard would it be to build back society?If there are people building rockets to make our species multi-planetary in case something goes horribly wrong, we should protect our knowledge if that same scenario happens.I mean, something like a bunch of bunkers all over the world with offline data centers storing most of our knowledge. Is there something like that that exists?

One of the roles of the libraries is preservation of knowledge. The problem that comes to my mind is the fact that there is a great amount of knowledge available only on non-paper media and you would need some kind of device to access them.
Even the old newspaper editions are either digitized or saved on microfiche films.
There is also a question of what does it mean to rebuild society? Get it to which stage? Bronze age, medieval times, time od space travels? Imagen if catastrophe was a masive EMP that would kill all of the electronic devices at once and that you have one simple task: bring fresh water to people. You can either start with building aqueducts (like old Romans did) or you could try to build pumps that run on wind power. How long would it take to create one single engine that is powered by electricity?

People overestimate the importance of the Internet, and computer systems in general, for storing knowledge. Most of humanity's knowledge, and all of the critical knowledge, is stored in books. Many of those are printed on acid-free paper, which is well-known to survive centuries with essentially zero maintenance.As long as people don't forget how to read, it's mostly a matter of repopulating the Earth and using libraries as a knowledge base. Even if the knowledge stored in the brains of all surviving humans was somehow wiped out, this should get us back to roughly the start of the 20th century in a relatively short time, and from that point on we can simply expect history to repeat itself (hopefully, without the "catastrophe" though).

I think it is important to remember that people and their knowledge and skills are critical. Given even perfect retention of written knowledge, you would need a massive learning program, maybe over generations.Since we are only talking about maybe 50 years of knowledge lost (the rest being in books), getting people to a point of being proficient would take much longer than than that. So starting again doesn't look so bad.

There are people working on this: https://en.wikipedia.org/wiki/Arch_Mission_Foundation
Of course it assumes a minimal skill to be able to extract the data.
So if society goes into the dark ages again, we would have to rely on books until society had developed the technology to read the media left behind.
