I remember the local village library books only had dates on the borrowing slips.<p>My library card was a 5x5cm card sleeve. If I borrowed something, the return date was stamped in the book, and on the book&#x27;s removable 5x15cm slip. That slip was put inside my card, and probably ordered by due date in the librarian&#x27;s index file.<p>This was early 1990s in Britain.
