The Gateway Arch National Park Archives is charged to preserve records and manuscripts that document the administrative history of the park and its associated themes. As the corporate memory of the Gateway Arch National Park formerly Jefferson National Expansion Memorial, the Archives also makes its resources available to the public in accordance with objectives outlined in the park's Statement for Management: To enhance and enlarge public understanding and appreciation of the significance of 19th century American westward expansion and of the related individual significance of the Old Courthouse, the Arch, and of the early development of St. Louis.
The archives is open to the public for research. Materials may not be checked out, but may be used in the library reading room. Please see our research procedures.
The archives contains 39 individual collections. Most of the collections contain material relating to the development and administration of the Jefferson National Expansion Memorial site, including the construction of the Gateway Arch and the Museum of Westward Expansion. Other collections contain materials that relate to the park's main theme of St. Louis's role in the settlement of the American West. See a list of the processed collections.
