Governments have continuity of government plans, business have BCPs etc, but on an individual level most people don't put too much thought in digital preparing for a "fast crash" scenario in which the Internet, telecommunications, and even the electric grid goes offline.
I'll start with an example, low hanging fruits first... in a fast crash scenario in which the Internet is cut and power is lost, and there is uncertainty of whether or not you can shelter in place or have to be on the move/run etc.... it would be best to focus on the smallest form factor computational/digital devices first, as they offer the most power efficiency thus making planning much more practical.
For example, mobile phones use much less power compared to desktop PC or even laptops. Kindles use even less power but aren't as general purpose or versatile as a smartphone. For all intents and purposes a modern smartphone IS a computer.
An offline copy of Wikipedia with all texts and images is currently around 85GB and can fit on a 128GB microSD card. You can get the free kiwix.apk app on your phone and mount a microSD with the offline wikipedia and you will have enough reading material to last you 10,000 lifetimes.
The rate limiting factor will be how to keep your phone powered long term sustainably. Something like an Anker 21W 2-Port USB Portable Solar Charger would do it when there is sunlight, otherwise a hand crank power generator would come in handy when there isn't broad sunlight.
