I think it's a bit fanciful to believe that post-apocalyptic people would have any interest in studying or learning from the past. Archeology is a very recent invention. Mostly, people just looted whatever old things they found for their immediate use or destroyed them because they didn't matter. The world will be awash in old crap by then too or if it isn't, the time capsules you leave will be just as gone as everything else.
