Native American People Photography By Edward Sheriff Curtis

Curtis archive at the Library of Congress
The Prints and Photographs Division Curtis collection consists of more than 2,400 silver-gelatin, first generation photographic prints — some of which are sepia-toned — made from Curtis's original glass negatives. Most are 5 by 7 inches (13 × 18 cm) although nearly 100 are 11 by 14 inches (28 × 36 cm) and larger; many include the Curtis file or negative number within the image at the lower left-hand corner.
The Library of Congress acquired these images through copyright deposit from about 1900 through 1930. The dates on them reflect date of registration, not when the photographs were taken. About two-thirds (1,608) of these images were not published in the North American Indian volumes and therefore offer a different and unique glimpse into Curtis's work with indigenous cultures. The original glass plate negatives which had been stored and nearly forgotten in the basement of New York's Morgan Library were dispersed during World War II. Many others were destroyed and some were sold as junk.
