They were the hub of the library. Dozens of small drawers just large enough to hold an index card awaited each patron that entered the building.
With paper and pencil in hand, patrons stood thumbing through the listings ready to jot down the coded typewritten numbers from cards that would direct us to the precise aisle housing the book we were searching for.
All of those perfect drawers all the same size... Each having it's own label so you could tell what is exactly inside...
The perfect invention for a person with OCD!
I'm on the hunt for the perfect invention, The Library Card catalog!
