Great Idea as a Wedding Favor or an Anniversary Party Favor! Give Your or You & Your Spouse's Favorite Book as Favors. Wrap in Brown Paper and add Library Card (templates) for the Gift Tags! Can be given as a Great Gift too!
Assign each table a different anniversary year (i. table 1 would be anniversary year etc.) and let the guests at that table write notes to be opened on that particular anniversary year (a unique alternative to a wedding guest book).
