The CGS Library will continue to follow Alameda County COVID protocols, open only by individual appointment. Click here to register for Library visits – you must register in advance! Details — COVID_19 Mitigation page. We will not be reconvening any in-person committees or Special Interest Groups until further notice. Groups may meet online.

Providing additional Online Resources on our website is a priority. These resources include lineage charts developed by our members, which provide finding aids and images. Search to find out if someone you are researching is included.
