 The scientific activity of Giorgio Roster (1843-1927) covered a great range, including medicine, climatology, and mineralogy. His experimental work brought him into contact with the early use of photography, which he appreciated immediately as an essential aid to scientific research and instruction. This first digital library version dedicated to his contributions clearly demonstrates his varied interests.
