The mission of the library is to provide information, educational and recreational materials, and lifelong learning opportunities to all residents of Siskiyou County. The library offers books, magazines, newspapers, media and electronic resources for county citizens free of charge. The library also supplies public Internet access, Interlibrary loan services, and delivery of materials between its 12 branch sites.
Citizens throughout the county can find a library to use as there are 12 facilities which provide public computers and traditional library materials. Although some of the branches are small in size, patrons have access to all of the materials in the system through a weekly delivery service. Branches are located in the following areas: Yreka, Montague, Dorris, Tulelake, Fort Jones, Etna, Happy Camp, Scott Bar, Weed, McCloud, Mt. Shasta and Dunsmuir. To help provide these rural communities with a public library, Siskiyou County Library partners with the cities, service districts and Friends groups to share costs.
