Salt prints are located in libraries, archives, and museums throughout Harvard. The holdings include images that document research undertaken by the University, were collected on the basis of the teaching and research interests of a particular repository, or come from the papers of professors and alumni associated with Harvard. The many thousands of photogenic drawings, paper negatives, and salted paper prints in the Harvard collections underscore the ubiquitous use of the salt print process for a variety of applications from portraiture to map making.
Architectural, landscape, and documentary views of the United States, Great Britain, Europe, and the Middle East reside at the Fine Arts Library, Harvard Art Museums, Harvard Map Collection, and Houghton Library. Diverse styles of portraiture are represented in images of Native American delegations in Washington at the Peabody Museum of Archaeology and Ethnology; early class portraits at the Harvard University Archives; and professional portraits of botanists, doctors, natural historians, lawyers, and performers at the Andover-Harvard Theological Library, Ernst Mayr Library of the Museum of Comparative Zoology, Gray Herbarium Library, Harvard Law School Library, and Harvard Theatre Collection. At the Fine Arts Library, scholars can find stunning examples of individual portraits, group photographs, as well as fine examples of photo montage, and hand-applied art work including hand-coloring and retouching from well-known nineteenth-century studios.
