National Museum of the American Indian - Smithsonian InstitutionThe National Museum of the American Indian (NMAI) has one of the most extensive collections of Native American arts and artifacts in the world—approximately 266,000 catalog records (825,000 items) representing over 12,000 years of history and more than 1,200 indigenous cultures throughout the Americas. Ranging from ancient Paleo-Indian points to contemporary fine arts, the collections include works of aesthetic, religious, and historical significance as well as articles produced for everyday use. Current holdings include all major culture areas of the Western Hemisphere, representing virtually all tribes in the United States, most of those of Canada, and a significant number of cultures from Middle and South America and the Caribbean.
