I haven't maintained it like I told myself I would, but regarding an offline repository of useful data, I made a school project a while back that aimed to fill that very niche. It was composed entirely of open source, public domain, and creative commons software, documentation (including survival guides and whatnot), and blueprints (eg buildings, greenhouses, farm equipment, tools, etc) for somebody with no internet connection, and it all fit on 16GB. Originally I distributed it under the Other -> Other category of PirateBay mostly for kicks because it was all free to share and I enjoy the distributed nature of torrents.
I've been tempted to go back and do it better, but then a career and life hit me.
It can be found at signalbundle.com for anyone interested, though I warn you that it's pretty long in the tooth at this point, and I eventually opted to host it on Google Drive for availability reasons, but it's still there if anyone's curious and/or has feedback. :)
