One of the ways that the Digital Public Library of America (DPLA) showcases its growing collections - DPLA hit ten million items in April 2015 - is through exhibitions. This Land Is Your Land presents materials from several DPLA contributors, including Clemson University Special Collections, Yellowstone National Park, and Great Smoky Mountains National Park. The images are organized into 6 themes: Building the Parks, Interpretation of Parks, Landscapes, Protecting the Parks, Stewards of the Parks, and Wildlife and People. Several of the themes include sub-themes; for example, first select Stewards of the Parks to access the landing page for this fascinating sub-collection. From there, use the "Next" button to move on to The Stewards of History at Andersonville National Historic Site sub-theme for individual and group shots of rangers at Andersonville National Historic Site, a park that is located on the grounds of Camp Sumter, a Civil War prison camp. Visit the From Superintendents to Assistants sub-theme for a few photos of some of the other staff in National Parks who are not park rangers, such as superintendents and their secretaries.
