While snooping around the library (since the entire universe isn’t on the web just yet), I went to use the book search computer — the modern equivalent of the card catalog. In the old days, there were tiny wooden boxes full of little pieces of scrap paper so you could write down Dewey Decimal numbers and such on top of the huge cabinets of alphabetical drawers. Next to the computer there was scrap paper, too — old cards from the old catalogs! It just didn’t feel right to write on them. I brought one home to cherish for future generations.
