The library holds an auction every year for equipment that's ready to be replaced.
Up for grabs this year - library card catalogs, that acted as the book database before computers came along.
Library staff members say these items have sparked a lot of interest.
"Since it's a sealed bid process, we have no idea what kind of amounts we're getting. So a lot of people bidding may think there's no way they have a chance for this, but we don't know what the bids are so you might as well send in a bid. You never know, you could end up with one of these, and we think it would be a great treasure to have," said Library Director Stephanie Patterson.
The library is accepting bids until September 30th. All proceeds from the auction go back to the library.
