The American Anthropological Association (AAA) is "the world's largest organization of individuals interested in anthropology." The site contains anthropology news and resources for students, teachers and researchers.
The Anthropological Papers, published continuously since 1907, are monographic volumes that include some of the great ethnographies of the 20th century, particularly on North American Indians. Several illustrious anthropologists published their work in the Anthropological Papers, as well as many past and present curators of the AMNH Division of Anthropology. Prior to 1930, large special reports were published in the Memoirs.
"The Library of Congress presents the National Jukebox, which makes historical sound recordings available to the public free of charge. The Jukebox includes recordings from the extraordinary collections of the Library of Congress Packard Campus for Audio Visual Conservation and other contributing libraries and archives. Recordings in the Jukebox were issued on record labels now owned by Sony Music Entertainment, which has granted the Library of Congress a gratis license to stream acoustical recordings." ~ from the website
The recordings include a wide variety of music, operas, ethnic characterizations, comedies, monologues, dialogues, recitations, blues, whistling, speeches, yodeling and more. The recordings are available in streaming audio only, and not available for download.
