The National Museum of American History, part of the Smithsonian, is home to more than 1.8 million objects and more than three shelf-miles of archival collections. This extraordinary national collection encompasses everything from the original Star-Spangled Banner to Abraham Lincoln’s top hat; from the first computer bug to the first artificial heart; from Dizzy Gillespie’s angled trumpet to Dorothy’s ruby slippers from The Wizard of Oz. The archival collections include a remarkable array of American history in documents, photographs, and other works, including major holdings on the histories of American business and music.
