Marriage Records – The California Marriage Index (1960-1985) can be accessed online. This is a master index to marriage licenses on file in the Office of Vital Records in Sacramento - it does not contain copies of marriage licenses. The actual records for marriages of individuals in Santa Clara County can be obtained through the Santa Clara County's Office of the Clerk-Recorder.

Birth Records – The California Room does not hold a collection of birth records. However, the indexes below can assist in the search for birth records. Please note that indices are not the actual records themselves, but a list of compiled data. Please refer to the Santa Clara County Clerk-Recorder's Office for official documents.​

Death Records – The California Death Index (1940-1997) is available online. This is a master index to deaths on file and does not contain copies of death certificates.

The Social Security Death Index has entries from 1962 to recent months and can be found online.

Obituaries – See our Obituary Searching guide for tips on finding an obituary.

Great Registers – Great Registers are alphabetical lists of all registered voters in a given county. Great Registers can help locate most male citizens between federal census years through 1944. At minimum, the Great Registers list name, age, and address. These records may also help determine the exact residence of an individual, how long they lived there, their occupation at the time of registration, and for some years their naturalization status. Searching for an individual in San José requires knowing the precinct number. The following Great Registers can be found in the California Room:

  • Santa Clara County Great Register
    Hardback: 1867, 1879, 1880, 1884, 1890, 1896
    Microfilm: 1900-1944
  • City of San José Great Register
    Hardback: 1946, 1948, 1950, 1952, and 1956

San José City Directories (1870-1979) – City Directories have listings by street name and surname beginning in 1913. Before this they are by surname only. To be listed, a person or property must have been located within city limits when the directory was issued. Early San José directories include other cities in the area; the City Directories Index will help you determine coverage. An index key at the front of each directory will give you valuable information in deciphering symbols and abbreviations. In some of the older directories, occupation and ownership of property is listed. See our City Directories page for more information on how to use this resource.

Census Records – The United States population census records are useful in researching family histories. There was a population census taken in 1790 and every 10 years thereafter. The California Room holds Santa Clara County census records on microfilm from 1850 – 1930, with the exception of the 1890 census schedules, all of which were destroyed by fire in the Department of Interior in Washington D.C. in 1921. Individual records from the federal population censuses are confidential for 72 years, by law. The 1940 census became available digitally in 2012 through the National Archives. Most census indices and schedules can be found online through free websites such as, the Internet Archive, and others. While the schedule of questions asked in the population census have changed overtime, the records contain at minimum the "Name," "Age," "Sex," "Race," and "Occupation" of residents at a given address.

County Histories – County Histories (1870s -1920s) are often referred to as "Mug Books," because of the biographical sketches in the original publications. County histories include information on early merchants, businesses, and many aspects of early local history and the local inhabitants who paid money to have their biographies included. The California Room has a collection of California County Histories that can be viewed during open hours.
