King County Library System Foundation

The King County Library System Foundation promotes literacy, learning, and libraries by providing support beyond public funding for initiatives and resources that enable the King County Library System to better serve the needs of our community. Since it was established in 1942, the King County Library System has grown its collection and locations to what you see today - 50 libraries, a collection of 4.5 million items, and 10 million visitors annually. KCLS and the KCLS Foundation work together to offer core library services while making creative ideas and pilot programs possible.
