The Official History of Australia in the War of 1914–1918 is a 12-volume series covering Australian involvement in the First World War. The series was edited by C.E.W. Bean, who also wrote six of the volumes and was published between 1920 and 1942. The first seven volumes deal with the Australian Imperial Force while other volumes deal with the Australian Naval and Military Expeditionary Force at Rabaul, the Royal Australian Navy, the Australian Flying Corps and the home front; the final volume is a photographic record.
