Sonoma Historian 2026, Vol. 64, No 4

The Fall 2026 issue of Sonoma Historian explores how Sonoma County’s history is preserved and shared, from historic buildings and archives to personal memories and art. Inside, readers will find Heritage Network updates, news briefs on local historical activities, and reports on preservation efforts involving Windsor’s oldest house, the Sonoma County Archives, and Rohnert Park’s historical collections. Feature articles revisit Christo and Jeanne-Claude’s Running Fence on its 50th anniversary, explore the History & Genealogy Library’s Playback Memory Lab, and highlight efforts to preserve sculptures honoring Charles M. Schulz. The issue also examines Sonoma County’s earliest published history, commemorates Francis Drake’s 1579 California visit, and reflects on successes and losses in historic preservation.
