Format, rather than subject content or provenance, is the basic criterion for
inclusion in the present finding aid. While the core formats are cased photographs
of the 1840s, 1850s and 1860s, related materials are also included. Daguerreotypes,
ambrotypes, tintypes (or ferrotypes), and collodion positives on leather or cloth
(pannotypes) are the typical media which fall under the definition of cased
photographs. In addition to these, the present finding aid contains some media with
physical characteristics similar to these, such as opalotypes, crystoleum
photographs, and some painted miniatures. For explanations of these media and
processes, refer to the Glossary of Terms, below.
ca. 515 items (chiefly daguerreotypes, ambrotypes, and tintypes) and ca. 85
photographic prints (salt prints).

of the physical items and is not intended to include or imply permission of the
copyright holder, which must also be obtained by the user.
