Carol Shull, Interim Keeper of the National Register of Historic Places and Chief, Heritage Education Services, National Park Service, developed the concept for the itinerary, edited it, and managed its production. Dr. Alan M. Kraut, historian and professor at American University, wrote the essay “America, the Nation of Nations.” Mr. James A. Percoco, historian and teacher at Springfield High School in Springfield, Virginia, wrote the essay “Divided We Stand: Markers of Conflict and Change on the Landscape.” Dr. Robert Sutton, Chief Historian of the National Park Service and manager of the Park History Program, wrote the essay “The National Park Service: Preserving the Places and Stories of America’s Diverse Cultural Heritage.” Cynthia Jarrin, Seth Tinkham, and Cassie Ward wrote most of the content and selected many of the photos. Brittany Bowers, Elizabeth R. Morse, Rebecca Reese, Zachary Lifton, and Zachary Siegel contributed written material, editorial comments, and wrote some site descriptions. Units of the National Park System featured in the itinerary and their staffs provided a number of images and other information. Kristin Roberts, Katherine Orr, Jennifer Jablonsky, Zachary Siegel, Matthew Klein, James Nelson, Nancy Bazar, Emma Byrnes, Adam Rubin, Tomas Ramirez, Thomas Hardej, Elizabeth Morse, Brittany Bowers, Mae Maginnis, and Alex Knabe also assisted in the preparation of the itinerary while serving as graduate and undergraduate student interns for the National Park Service Heritage Education Services. Cassie Ward programmed the itinerary into the template. Hyejung Kwon designed the original computer template for the itineraries as the practicum for her Masters of Tourism Administration (MTA) at George Washington University’s School of Business, Department of Tourism and Hospitality Management. Kathryn Warnes, contractor with the National Conference of State Historic Preservation Officers, has adjusted the template.
