The Okanagan Historical Society (O.H.S.) has, since 1925, published an annual report composed of articles, stories and other material chronicling the history of the Okanagan Valley. The comprehensive information appearing in these volumes provides context and background to complement the primary sources available in other Digitized Okanagan History collections. We are indebted to U.B.C. Library Digital Initiatives for sharing their PDF copies of this publication for our project.
