Official List of Officers of the Officers' Reserve Corps of the Army of the United States: Officers residing in Illinois, Wisconsin, Minnesota, Iowa, August 31, 1919

This volume was published by the United States Adjutant-General's Office in the immediate aftermath of the First World War. Following the Armistice, the War Department prioritized the formal organization and documentation of the Officers' Reserve Corps, a central component of the National Defense Act of 1916. This specific regional directory provided a structured accounting of commissioned officers residing within the Sixth Corps Area, serving as a functional administrative tool for post-war military mobilization and record-keeping.

The publication follows the utilitarian design conventions typical of early twentieth-century government records, prioritizing clarity, accessibility of data, and bureaucratic accuracy over aesthetic ornamentation. It was intended for internal distribution among military personnel and governmental departments to ensure effective communication channels between the service branches and their reserve components. Its historical value today lies in its role as a primary source document for genealogists and military historians tracking the professional paths of service members during the demobilization period of 1919.
