I’m a wealthy billionaire dying of terminal illness. The world I’m currently living in is clearly on the brink of a world ending nuclear war. I predict that the world ends next month. I am putting together a large “time capsule” of sorts, for future people in the post-apocalyptic world to use to rebuild.

I am able to use 5 billion dollars on my little project. My question is, what would be the most valuable tools/information to stock my Time Capsule with? The purpose of it is to help people reduced to about 1890s style living make their way back up to modern standards of living.

By 1890s tech, I mean industrialized production is in its infancy, most people farm, infrastructure in smaller towns is lacking, and no motorized transportation.
