When the United States needed to teach soldiers and others about public health matters, who did they turn to? The United States Army Pictorial Service, of course. The National Library of Medicine has digitized 18 of these most intriguing items for consideration by researchers as well as the general public. These short films cover women's health, physical fitness, syphilis prevention, as well as malaria prevention. First-time visitors may want to start with the "Criminal at Large" film which presents a fascinating look at how to prevent malaria in rather dramatic fashion. Also, "Winky the Watchman" is an animated treasure that is designed to help parents promote their children's oral hygiene.
