The Mendocino County Historical Society maintains the Held-Poage Research Library at 603 West Perkins Street in Ukiah, California 95444. Their website is http://www.mchs.ws.
While working on one of my long-standing authorship projects, I enjoyed visiting the Mendocino County Historical Society’s library in Ukiah, California. The library is housed in a 1903 Victorian home, recognized as a historic landmark, at Perkins and Dora Streets – not far from the center of Ukiah. Open Wednesday to Friday, 1 PM to 4 PM, the library is staffed by volunteers knowledgeable as to the history of Mendocino County.
This repository has just what one would expect from a historical society. There, you will find a fair-sized collection of genealogical references from all over the country, and collections focused on the region and Mendocino County: telephone books, school annuals, old maps, and photographs. The county’s Great Register from 1865 to 1970 is available.

I was delighted to tour the newly built archives building on the same property. This building will house extensive archival collections. Patrons will use the first-floor Reading Room. On the day of my visit, things were still being moved in. This will be a terrific resource very shortly.
Parking on the street. Eats on State Street a few blocks away. Try the Ukiah Brewing Company.
Donations to the Mendocino County Historical Society are greatly appreciated.
