"It can hold a gigantic amount of invaluable information." Which can only be extracted by somebody hand-copying it down. Possibly we can work up some sort of photograph-based system to just graphically copy it to a book or something, though. Which is also the only hope you have of extracting the map data, too. This is the sort of thing I mean; things you take for granted as being valuable have huge chunks of their value chain hacked away. Audio content would be the easiest to deal with; cell phones would output master-quality recordings of whatever music you may have, because 1960 cables are still bigger than your phone's little jack, but at least they can fabricate a smaller one, electrically compatible with what they already have.
