Research and Library

Explore Oregon’s History

With resources that document significant people, places, and events that have shaped Oregon’s history, the Oregon Historical Society is an invaluable destination for researchers. Our resources include the OHS Research Library, the Oregon Historical Quarterly, and online digital collections and publications, such as the Oregon Encyclopedia and OHS Digital Collections. We invite you to explore the world’s largest collection of Oregon-related materials—all our resources are available to everyone.

Please note that the OHS Research Library is undergoing an extensive renovation, and the downtown reading room is closed through late 2020. Researchers will still have access to reference services during the renovation; please contact with your reference inquiries.
