Sonoma County Library Archives
The Sonoma County Library Archives includes the County of Sonoma' archives, as well as many of the Library's own archival collections. The County Archives contains official records of deeds, mortgages, wills and probate records, assessments of property, voter registration, oaths of office, surveys, maps, corporation records, business licenses and more. The Library's collections include the official records of Sonoma County schools, businesses, and of the Libary itself, as well as many other materials. Please check the Archival Collection Guides or the Library's catalog to search specific records (the search box in the left sidebar will limit your search to Archives only). Materials must be requested and will be brought from the Archives to the Library for your use. Call 707-308-3212 with any questions, or to request materials. Please allow five business days for volumes to be delivered to the library.
