Sonoma County Libraries - Open Libraries

The Sonoma County History & Genealogy Library is a community resource of immense value. The local history and genealogy collection was first established in the Santa Rosa Central Library’s California Room. In 1993, the collection was moved to a separate building located adjacent to the Central Library and commonly referred to as the “Annex.” In 2002, the Sonoma County Library Commission, governing board of the county-wide library system, adopted a new mission statement for the local history and genealogy division and renamed it the Sonoma County History & Genealogy Library. Services, resources, and technologies continue to grow to meet the demands of those we serve.

Some of the resources available include: 
  • Personalized one-on-one instruction in historical and genealogical research
  • Over 40,000 photographs, many of which are available online as part of the Sonoma Heritage Collections
  • A comprehensive collection of Sonoma County historical works, county, family, and property histories
  • Access to the Sonoma County Archives which hold many of Sonoma County’s earliest court, naturalization and tax records
  • The Sonoma County History Index which has thousands of references to County events, places and people
  • Santa Rosa newspapers on microfilm from 1857 through 1969, as well as other county newspapers for various locations and dates
  • Wide ranging newspaper clipping files
  • The California Indian Library Collection
  • On-line subscriptions to HeritageQuest,, GenealogyBank and the San Francisco Chronicle 1865-1922
  • Select California city directories and voter registrations
  • Sanborn Fire Insurance Maps
  • Indexes to local cemetery, marriage, birth, death and militia records
