The Northwest Room has a small, but significant collection of original documents of early Northwest History. These manuscript materials include exploration, missionaries, military campaigns, and documents related to early settlers. The earliest document is a handwritten letter from Father DeSmet in 1840. The collection also includes a handwritten diary kept by George T. Allan in 1841 on a trip from Fort Vancouver to Hudson's Bay. Other materials include letters from O. O. Howard, George Wright, and the Geary Collection concerning an investigation at the Lapwai Indian Agency in 1872. In order to make these materials more accessible, the Northwest Room has digitized some of the more significant original documents.
