The North Bay Historic Preservation Digital Collection is just one of the online offerings from the Sonoma State University Library. It's a fascinating collection, bringing together photographs and planning documents related to buildings and landscapes in and around this historically rich area. The photographs were taken by students enrolled in the institution's historic preservation program in the 1970s. A good place to start is by taking a look at the photos of the historic Stone House, which is the oldest building in Lake County. Visitors can also search the entire archive by keyword or look over the technical reports like the "Sonoma County General Plan for Historic Preservation." As a whole, it's a great way to learn about the rich cultural and architectural landscape of the area.
