The National World War I Museum and Memorial Online Collections Database

Created by the National World War I Museum and Memorial (Kansas City), these online collections are searchable and browseable. Still growing, they represent only a part of the museum's collections. In addition to extensive numbers of photographs, the materials include letters, posters, songs, and other materials related to the United States' involvement in the war. The museum and its collections have been in operation since 1920, but recently received status as a historic landmark (2006) and national memorial (2014).
