These resources may only be accessed in person at our research center and archive in Eureka, California. The Humboldt County Historical Society is in the process of acquiring the infrastructure necessary for digitizing delicate large-format documents. Thanks to a generous donation to purchase large-format scanners, we expect some of these resources to start becoming available online in 2019. You can continue to support our Digital Archive Project by becoming a sustaining member of our organization, commissioning research, or donating directly to the Digital Archive Project (link on Research Center page).
