The Friends of Arapahoe Libraries hosts two annual book sales to showcase a large selection of high-quality, gently-used materials available for purchase. In addition to the regular sale days open to the public, Friends members will receive postcard reminders for upcoming sales and exclusive access to the Friends Members' Preview Night the night before.

All materials purchased at the used book sales support initiatives at Arapahoe Libraries, from Summer Reading programs and events to building safe and inviting outdoor spaces.
