I don't have the skill, but it would be wise to build a collection of books that cover such fundamental skill set.
While I'm a decent programmer and I know a bit or two about networking protocols, I don't know anything about electronics.
But I would be happy to have in my own library this sort of civilization backup.
Unfortunately, I'd have no idea where to start.
@Shamar I would start with simple things that interest me first. Everyone has their own interests so hopefully a group of people doing the same thing will ensure there's a wide enough selection
In my case, I started with books on cabin building and simple living. Construction and shelter will be pretty important after a collapse

@Shamar This is a good thing to do even in case there's no risk of collapse. The best networks can have failure modes that are hard to diagnose and fix. In such circumstances, offline (and off power) systems of data like books would be extremely useful
