There is a vast number of quality PDFs available online, for free.
Compiling a small library of downloaded PDFs regarding things you might need to Google is not a terrible idea.
My collection includes:
Automotive maintenance
Firearm maintenance
First aid and wound care
Human anatomy and biomechanics
Medicinal herbs identification
Foraging guides
Hunting guides
Farming principles and best practices
Preserving food
I have access to knowledge that otherwise would rely on someone else's server, and even a functioning grid.
Will I ever need it? Probably not. Hopefully not. But it's a minor time and effort expenditure to hedge risk. Decentralize what you can.
