Washington's Secretary of State's office has been pretty innovative in bring yellowed-paper archives out of their boxes in cool storage and into the digital age. The state's Digital Archives has scanned in -- and hand-indexed -- years of territorial newspapers, old marriage and other personal records, and photographs, among many other things.
A new feature: a searchable online database to find records of World War I veterans. The paperworks lists training, battles, wounds, birthplaces, and race (Welcome to 1919: "Race: White or colored", with that capitalization.)
The information cards don't provide many details, but they give a glimpse into a life. Here, for example, is the March 12, 1920 record for a Pfc. Alexander D. Munro, a Spokane man who was born in British Columbia and enlisted at age 32 for a tour that saw him overseas in the final months of the war. He served in the "QMC," which I'm guessing was the Quartermaster's Corps -- the Army's supply arm -- and was overseas from July 1918 to April 1919.
