Research Resources

The Oregon Historical Society provides several online resources for researching Oregon history, including expert scholarship and access to digitized objects, photographs, maps, textiles, artworks, manuscript materials, books, films, and oral histories preserved in OHS’s vast collections. OHS offers a range of resources that are appropriate for every grade level, making it easy for educators to include primary sources, scholarly articles, and previously recorded lectures in their lessons.


Many of OHS’s digital history resources were developed with classrooms in mind. Our digital history projects, including The Oregon Encyclopedia and the Oregon History Project, cover a wide range of topics through short, peer-reviewed entries written by experts from across the region.

The Oregon Encyclopedia

The Oregon Encyclopedia (The OE) is a statewide digital resource of history and culture. It is the authoritative and creative resource on all things Oregon, a substantive and lasting recognition of the state's complex history and culture. Most of The OE’s 1,700+ entries are short, comprehensive summaries of Oregon topics, with longer essays tackling more extensive topics such as the Oregon Trail or Blacks in Oregon. Authors and editors review entries regularly to ensure that they include up-to-date information and sources.

The Oregon Encyclopedia

Oregon History Project

The Oregon History Project (OHP) offers narratives on Oregon, written by regional historians, as well as over a thousand digitized and annotated primary sources from OHS’s research library and museum collections. Items included in the “Historical Records” section provide important connections to geography, geology, economics, and art, and were selected for their relevance to Oregon Social Science Standards. The OHP is a powerful resource as it provides context on primary sources and connects researchers to related topics in OHS’s digital history projects.

Oregon History Wayfinder

The Oregon History Wayfinder is an interactive map that helps students visualize where history happened. All entries from the Oregon History Project and The Oregon Encyclopedia are searchable on the map, and results can be filtered by location, date, and theme.

The Oregon Historical Quarterly (OHQ) is a peer-reviewed, public history journal on Oregon and Pacific Northwest history. Featuring scholarly research articles, primary documents, reflections, and photo essays, OHQ brings well-written, well-researched history to general readers and is appropriate for high school students. OHQ is a tremendous resource for teachers seeking to bring into their classrooms a balanced representation of the diverse ethnic groups that continue to shape Oregon.
