Why Are Collections Important?
The Smithsonian's collections represent our nation's rich heritage, art from across the globe, and the immense diversity of the natural and cultural world.
The scope of objects in Smithsonian collections is staggering—from ancient Chinese bronzes to the Star-Spangled Banner; from a 3.5 billion-year-old fossil to the Apollo lunar landing module; from the ruby slippers featured in The Wizard of Oz to presidential memorabilia.
