About Arapahoe Libraries

Arapahoe Libraries was established in April 1966 to provide public library service to all residents of Arapahoe County, except those living in the cities of Littleton, Englewood and Aurora. Residents of these cities are served by libraries established prior to 1966 that are funded and maintained by their respective city governments. All Arapahoe County residents, however, are free to use any of the libraries in the county. Residents can also participate in the Colorado Library Card Program, which allows them to borrow items from any participating academic, school and public library in Colorado.

Arapahoe Libraries serves a diverse and varied population covering the rural areas of Byers and Deer Trail, the cities of Bow Mar, Centennial, Cherry Hills Village, Columbine, Glendale, Greenwood Village and Sheridan, and the unincorporated areas of Arapahoe County. Arapahoe Libraries is also a major resource for elementary and high school students of the Littleton, Cherry Creek, Sheridan, Byers and Deer Trail School Districts, as well as for those receiving private and home schooling, and students attending local colleges and universities.
