I am specifically asking about software and needed libraries, not stuff like Wikipedia or the writings of Ernest Hemmingway.
To keep people from archiving all of github on thousands of shucked external hard drives cobbled together all Frankenstein-y to create a postapocalyptic data center assume a ~1TB storage limitation. Though I’m sure that person exists here on Lemmy somewhere :D
Raspberry pi os , it can also be run on non raspberry pis*. all the recommended packages in its menu (libre office?) that should get you a nice os.
Some torrenting software to ensure you can help share it around.
I recently heard of something called a ‘Pirate box’ which is a WiFi router without a password and storage attached for people to upload and download stuff to / from .
I wouldn’t do it myself, but if it was a country town, it could be something similar to a virtual notice board in the pub.
