		Slides [subseries]: The Slides sub-series contains slides of the photographs of individuals from the General Photographs subseries, as well as about five hundred slides of the NASA Viking Mars mission. Due to his work in exobiology, Lederberg was involved in the Viking mission; these slides are his personal copies of images taken in space.
