A statewide, collaborative digitization project investigating the state’s involvement in World War I.
http://missourioverthere.org/Since 2012, Museum of Osteopathic Medicine and International Center for Osteopathic History has collaborated with organizations across Missouri on a statewide digitization project, Over There: Missouri & the Great War, with a mission, to create an online collection of Missouri World War I documents and artifacts. More than 14,000 pages of letters, diaries, photographs, military records, and other original materials have been placed online for free public access. Missourioverthere.org also features hundreds of artifacts from the war and civilian support organizations.
