We recently purchased the contents of two buildings about to be demolished in small Ohio towns: a bank and a former general store. Both had records, paperwork, books, journals, advertising, ephemera, billheads, etc. going back to the 1800s stored in closets, basements, attic areas, etc. I couldn't even guess as to the number of items in these two acquisitions, but it did fill up two 26' box trucks.
