Sno-Isle Libraries serves 728,745 residents in Washington's Snohomish and Island counties through 22 community libraries, online services, and Library on Wheels encompassing 2,260 square miles.
The Sno-Isle district dates from 1944 when the Snohomish County Rural Library District was established by a vote of residents in the unincorporated areas of Snohomish County.
Voters in Island County established an Island County Rural Library District in 1962, following a successful demonstration of library service on Whidbey Island by the Snohomish County Rural Library District. County Commissioners from both counties jointly created the Snohomish-Island Inter-County Rural Library District in December 1962.
The district's Board of Trustees adopted the name Sno-Isle Libraries, reflecting the common interest of providing quality library services to residents of both counties.
