In conjunction with the National Park Service, Clemson University has digitized over 350,000 cultural heritage objects and 1.5 million pages of unpublished sources housed in over 20 national parks and historic sites. All images are high-resolution and downloadable.

Each park’s page contains a number of source collections, generally grouped by topic or time period. Open Parks Network allows users to find sources in a number of ways. Users may search by park, source collection, or keyword. For instance, the user can choose to see all collections and items from Andersonville National Historic Site by clicking on the park’s name.

Alternatively, users can navigate directly to a collection of Outer Banks Shipwrecks by browsing an overview of each park’s collections. Open Parks Network also features a map illustrating the number of sources from each geographical location that users can use to access sources. Each of these options are conveniently located in a single “Explore” tab.

The classroom utility of Open Parks Network’s sources varies widely. While the sources within some collections could be beneficial for classroom source analysis and research (e.g., the collection of Civil War Newspaper Illustrations on the Fort Sumter National Monument page), other collections would be of greater use to those with a specialized interest in a park’s operational history (e.g., the collection of Kings Mountain National Military Park Personnel). None of the sources come with any descriptive text, which can make it difficult to contextualize sources.

Instructors and students may find Open Parks Network useful for a variety of classroom activities, including using sources to encourage historical thinking about the past that the parks memorialize or about the parks themselves. This site might be of particular interest for teaching about the National Park Service, given its centennial anniversary in 2016.

Visitors to this site are invited to explore historical aspects of the roughly 200 National Park Service locations designated important to U.S. history and prehistory. Materials are organized by "cultural resource subjects," including archeology, architecture and engineers, cultural groups, cultural landscapes, historic buildings, mapping, maritime and military history, and "cultural resource programs," such as the American Indian Liaison Program and Heritage Preservation Services.

Visitors can search for information on more than 2.5 million Civil War soldiers and sailors; more than 71,000 properties listed in the National Register of Historic Places; and approximately 240,000 reports on federal archaeological projects in the National Archaeological Database. National Register Travel Itineraries provide historic guides to 18 cities and communities. The National Underground Railroad Network to Freedom contains information on 51 sites of importance and on slavery and antislavery efforts.

Also of interest are bibliographies on the African American west and public history, and full-text publications on the Antiquities Act of 1906 and the promotion of the city of Seattle during the gold rush era. The homepage—"History and Culture"—presents several topical, comprehensive historical exhibits including the "Eisenhower Virtual Museum."

Funded by the Rockefeller Corporation and part of the Library of Congress American Memory Project, this site features approximately 200 maps that document the history, cultural aspects, and geological features of the areas that became the Acadia, Grand Canyon, Great Smoky Mountains, and Yellowstone National Parks. The maps date from the 17th century to the present and include early European, exploration, geological, environmental, United States Geological Survey, and National Park Service maps.

The site is divided into four sections, one for each of the featured national parks. Each section includes a 1200-word essay describing the history of the area and the process by which it became a national park, illustrated with five to seven maps.

The site also includes a bibliography of over 200 scholarly works on related topics. Other links include a 750-word general history of the mapping of national parks and a "Learn More About It" section that offers links to 14 Library of Congress Special Presentations and related collections and exhibits. The collection is keyword searchable and can be browsed by geographic location, subject, creator, and title. This easily navigable site is ideal for students and teachers interested in cartography, the National Parks system, and conservation in America.

This website gathers together documents concerning the history of National Park Service properties.

Navigation is simple. Just select your park of interest from the drop-down list, and you will be brought to a list of all of the available documents for that particular location. Documents include structure reports, administrative histories, physical and cultural landscape reports, studies of historic resources available, management regulations, conference proceedings, notes, and more.

Note that these resources largely explore the history of preserving a historical site, rather than the importance of the site itself. This is the history of making history public. The documents are most likely to be of use in the later grades, as they lean towards official language. However, there are also images such as floor plans and photographs within documents which may be of use when introducing a park into your discussions.
