Ever woken up in the morning wondering what happened to card catalogs? Probably not, that is unless your a retired librarian. If you’re old enough the words call number and subject heading might ring a bell.
The index cards with holes in them, neatly stacked inside of long narrow drawers had been the librarians Bible, packed with goofy number/letter combinations that made students’ heads spin. I can hear the ghost of library past now, “Go look it up in the card catalog. Go look it up in the card catalog.” Only a select few would attempt to show you where a book was. You were supposed to know because of that quick lesson you got about the Dewy Decimal System.by
