California Genealogical Society and Library

The California Genealogical Society and Library (CGS) helps people trace and compile their family histories. The Society maintains a library, gathers and preserves vital records, disseminates information through its publications and Internet access, and teaches genealogical research methods through meetings, seminars and workshops. Organized in San Francisco on February 12, 1898, CGS is one of the premier genealogical resources in Northern California. The Library is rich in genealogy reference materials, both standard and unique, covering people and places in California and the rest of the country. The Society offers research services, online one-of-a-kind genealogical indexes and databases, and a research library housing over 38,000 reference materials from California, the United States, and around the world.
