Used Books or Other MaterialsDonation bin at Main Library

The library welcomes donations of gently used hardcover and paperback books and media (DVDs, CDs, audiobooks). We cannot accept donations of cassette tapes, VHS tapes, mass market paperback books more than 5-years old, or magazines more than 1-year-old. For the full list of accepted items, see the Donated Books Guidelines.

Please bring your donations to the Main Library and place them inside the donations room on the right, inside the Arapahoe entrance (see the photo). If you are donating a few items, slide them into the donations slot in the wall. If you are donating bags or boxes of materials, enter the Donations Room and place them on the cart in the room.

The library may sell donated items at the Paper & Spine Used Bookstore, book sales, and through third-party sources. Donated materials the library cannot sell are recycled. The money raised through sales funds the volunteer program, special projects, and/or the purchase of library materials. Donated materials are not added to the library collection.
