Historical volumes are lined up together.

The Yellowstone National Park Archives preserves and makes accessible the history and science of the world's first national park. The manuscripts, photos, maps, films, oral histories, administrative records, and scientific data document the natural and cultural resources of the park as well as its development and management. The records are rich in topics ranging from geophysics, geology, and ecology to archeology, tourism, and history. An affiliated archive of the National Archives, the archives houses a unique record of physical and administrative development beginning with early civilian superintendents and pioneer entrepreneurs, through the turn-of-the-century military era, to the founding and development of the National Park Service.
