The U.S. National Park Service (NPS) presents the Petersburg National Battlefield in Petersburg, Virginia. The national battlefield commemorates the American Civil War Battle of Petersburg. The NPS offers information and materials about the history of the battle and visiting the park.

Now in a fully updated edition, this invaluable reference work is a fundamental resource for scholars, students, conservationists, and citizens interested in America's national park system. The extensive collection of documents illustrates the system's creation, development, and management. The documents include laws that established and shaped the system; policy statements on park management; Park Service self-evaluations; and outside studies by a range of scientists, conservation organizations, private groups, and businesses. A new appendix includes summaries of pivotal court cases that have further interpreted the Park Service mission.
