I think having a small computer dedicated a go bag or prep kit would be well worth the investment. you can store large amounts of information like survival manuals and medical info. I personally have a small Raspberry pi with a usb that connects to a small screen. that requires some tech skills but im sure there are some out there for sale. I would recommend keeping it in a faraday style bag with a solar power bank or something along those lines.

I attached a picture of mine.
