Bean, C.E.W., Gullett, H.S., The Official History of Australia in the War of 1914-1918 Volume XII – Photographic Record of The War (Angus and Robertson Ltd Australia, 1938).
The Official History of Australia in the War of 1914-1918 is a 12-volume series covering Australia’s involvement in the First World War. The series was edited by the official historian Charles Bean, who also wrote six of the volumes, and was published between 1920 and 1942. The books, with their familiar covers, “the colour of dried blood” in the words of one reviewer, rapidly became highly regarded internationally. Bean’s work established the tradition and set the standard for all subsequent Australian official war histories.
