Research & Collections
The OMM is a vital repository for historians, veterans, and families. Our collections contain more than 14,500 catalogued objects, plus more than 14,800 catalogued volumes within the Thomas E. Withycombe Library. Together, these collections trace the evolution of military technology and examine the roles played by Oregonians, their allies, and their adversaries throughout history.
Collections as Research Tools
Beyond our exhibits, our collections are available for research. Whether you are conducting academic study or researching family history, you may request access to specific artifacts or library and archives material. On-site research is by appointment only.
Main Collections: include uniforms, artwork, banners, personal effects, books, battlefield equipment, and more than 800 small arms (one of the largest publicly available firearms collections west of the Mississippi River) pertaining to Oregonians, their allies, and their adversaries.
Thomas E. Withycombe Library: houses more than 150 years of primary and secondary source materials, including publications, personal papers, photographs, and audiovisual recordings.
