I like OSM as much as anyone, but out of those four, it'd be fourth by a mile or two in terms of usefulness. The English Wikipedia (especially if including other Wikimedia projects) on its own would be practically enough to get humanity back to the current day if things were set back a few hundred years. The Internet Archive would be, too, and probably a bit further. OSM would just get you a slightly better map.

That said, 'jacquesm's comment is beyond stupid, really.
