The George W. Comstock Collection is concerned with his work for the International Tuberculosis Campaign in the 1940s and 1950s. This campaign was the first major disease control and research activity of the World Health Organization. The collection consists of three volumes: Mass BCG Vaccination Campaigns, 1948-1951; the International Tuberculosis Campaign, July 1948-June 1951 (First, Second, and Final Reports); and WHO Tuberculosis Research Office Selected Papers, 1949-1953. The reports were drafted by Dr. Johannes Holm of Denmark, who directed the campaign, and finished by Comstock after Holm's death. The collection also includes a 45-page manuscript from 1984 entitled "History of the ITC", a tuberculosis campaign bag that belonged to Dr. Lydia Edwards, and a photographic slide of a Danish Vaccination Team in Poland, 1947.
