In examining the 424 units of the U.S. national park system, geographers Joe Weber and Selima Sultana focus attention on the historical geography of the system as well as its present distribution, covering the diversity of places under the control of the National Park Service (NPS). This includes the famous national and the lesser-known national monuments, memorials, lakeshores, seashores, rivers, recreation areas, preserves, reserves, parkways, historic sites, historic parks, and a range of battlefields.



The geographic view of The Parks Belong to the People sets it apart from others that have taken a solely historical approach. The majority of units in the NPS are devoted to recreation areas or historic sites such as battlefields, archaeological sites, or sites devoted to a specific person, and this is reflected in the authors' approach.



What we think of as a national park has changed over the years and will continue to change. Weber and Sultana emphasize changing social and political environments in which NPS units were created and the roles they serve. The authors also focus on parks as public facilities and sites of economic activities. National parks were created by people for people to enjoy, at great cost and with great benefit. They cannot be understood without taking this human context into account.
