Web Information A climbing party in Glacier National Park, Montana, during the summer of 1925.
Lantern slides are big, heavy, and fragile, since they are made of glass.
Lantern slide projectors, once a fixture in fine arts courses, are now quite rare. This archive combines the one-time teaching collections in architecture, landscape architecture, and city planning, the three departments whose merger formed the GSD in 1936. Recently, visual resources librarian Ann Whiteside of the Loeb Library supervised the conversion of about 2,500 of the lantern slides to digital format. They offer a panoptic view of American culture between 1850 and 1920, especially its built environment. A grant from the Library of Congress and Ameritech funded the conversion.
