The origins of the National Anthropological Archives (NAA) date back to the pioneering efforts of explorer, military man, and scientist John Wesley Powell in 1879. Powell brought the organization into the fold of the Smithsonian Institution and since that time, the NAA has grown to include 635,000 ethnological and archaeological photographs, 20,000 works of native art, 11,400 sound recordings, and more than 8 million feet of original film and video materials. On their site, visitors can make their way through their online exhibits, guides to the collections, and take in information about ordering copies of photos, manuscripts, and recordings. Scholars will want to peruse the "Guides" area, which features information about the NAA's collections, including guides to the film archives and a guide to their anthropological fieldnotes and manuscript offerings. More casual users will appreciate their very fine online exhibits, which include ""Drawing the Western Frontier: The James E. Taylor Album" and "Camping With the Sioux: Fieldwork Diary of Alice Cunningham Fletcher".
