The personal archives of photographers Carlotta Corpron (1901–1988), Nell Dorr (1893–1988), Laura Gilpin (1891–1979), Eliot Porter (1901–1990), Erwin E. Smith (1886–1947), and Karl Struss (1886–1981) are prominent collection resources. Finding aids and guides for these and other monographic collections are available online under the Collections/Photographs/Learn More tabs on the ACMAA website. ACMAA photography collection contains early images of Americans at war, anchored by 55 Mexican–American War (1847–1848) daguerreotypes. The collection houses a copy of Alexander Gardner's two-volume work, "Gardner's Photographic Sketch Book of the Civil War" and a copy of "Photographic Views of Sherman’s Campaign" (1865) by George Barnard. A group of more than 1,400 nineteenth and early twentieth-century portraits of Native Americans that originated with the Bureau of American Ethnology is another of the collection’s highlights, along with a complete set of Edward Curtis's "The North American Indian".
