Written by Woodward, Smart, Otis, and Huntington under the direction of Joseph K. Barnes, Surgeon General of the Army. This massive, graphically illustrated set has been called the “first comprehensive American medical book”. It is one of the most remarkable works ever published on military medicine. An index of operators and reporters appears at the end of the third surgical volume. This index makes it possible to look up any surgeon, and find the patients he treated.
