Washington County Cooperative Library Services

Washington County Cooperative Library Services (WCCLS) is the library system serving Washington County, Oregon. WCCLS distributes tax funds to libraries. It was established in 1975.

Libraries
WCCLS is made up of 16 libraries which are operated by 13 cities and non-profit organizations.

Libraries that were formerly affiliated with WCCLS included ones in the former Tanasbourne Mall (before the Tanasbourne area was incorporated) and, in the 1970s, Aloha Park Library, located in Aloha Park school, which was open to the public one night a week.

In 2019, the Oregon College of Art & Craft Library closed along with the rest of the college. Additionally, the Tuality Health Resource Center closed in August. These specialty libraries had been affiliated with WCCLS for many years, and some of their collection was distributed to other libraries in the county.
