The evolution of business is inextricably linked with American and international history and identity. You can now explore this aspect of American and international life via catalogs, pamphlets, advertising materials, and ephemera on essential industries that emerged in the nineteenth and early twentieth centuries — steam engines, railroads, motorized vehicles, agricultural/farm machinery, building and construction, mining, and more. The collection exposes technological advances over time, changes in fashion/design, architectural advances, societal changes, and business history. Trade Literature and the Merchandizing of Industry is comprised of items selected from the National Museum of American History, and contains about one million pages of primary source content.
