Research and Library

Explore Oregon’s History

The Oregon Historical Society’s research library and the Oregon Historical Quarterly are invaluable resources for learning about the past and providing context on our present. Our library preserves the world’s largest collection of Oregon-related materials, documenting the people, places, and events that have shaped Oregon’s history. Visitors enjoy broad access to our materials, both in our downtown reading room and online through our digital collections, digital history resources, and free scholarly articles.

The research library remains closed for renovations that began in January 2020. To learn more about library services during the renovation, please visit
