This is worth repeating: Kate over on Adventures in Library Land highlighted an AbeBooks article that listed a few examples of things that were found in used books:
- Forty $1,000 bills
- Piece of bacon
- Credit cards
- Valuable baseball cards
- A diamond ring
I'm sure most libraries have a collection of odd things, too - just this week I found a Pokémon card (in a book about dealing with bullying). I tend to use receipts myself, or whatever random scrap of paper is handy at the time. Perhaps there should be a Where's George?-like program for bookmarks, too.
