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.
