The California Historical Society was founded in 1871. A nonprofit, privately funded, membership organization, CHS is the state's official historical society. Its mission is to engage the public's interest and participation in collecting, preserving, and presenting art, artifacts, and written materials relevant to the history of California, and to support historical research, publication, and educational activities.
The Conference of California Historical Societies was founded in 1954 as a federation of historical societies, museums, libraries, and other history-oriented groups and individuals. CCHS helps historians, and others who are interested in history, to connect and share information -- joining efforts to preserve records, artifacts, sites, and buildings. CCHS also helps local societies and small museums with skills in management, acquisition, preservation, and restoration techniques.
The California Archaeological Site Stewardship Program (CASSP) is a statewide program, directed by the Society for California Archaeology. Volunteers attend a two-day training workshop before they become site stewards. Site stewards work in their local areas, in teams coordinated by a professional archaeologist who works for the land management agency responsible for the sites. CASSP volunteers regularly visit assigned sites on public lands and report on their conditions to their local coordinating archaeologist, who works for the land management agency responsible for the sites. By consistently monitoring the sites, problems are detected early, when they can more easily be corrected.
