From the Barnum House ARchive

Map Collection

Large format maps are some of the most difficult historical resources to preserve. Many of the items in this collection are unique to the Barnum House archive and in dire need of preservation by digitization.

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).
