This is a really neat idea. Each table has a number so have everyone from that table leave you a note for your anniversary that year. Maybe not whole books though, as it says on the thing. Perhaps a small notepad that can be easily stored, along with the others, in an old purse, and quickly decorated with stuff to make them identifiable.
