Natural Resources and the impact on the economy in the regions

The Mapping the National Parks collection documents the history, cultural aspects and geological formations of areas that eventually became National Parks. The collection consists of approximately 200 maps dating from the 17th century to the present, reflecting early mapping of the areas that would become four National Parks, as well as the parks themselves. Production of this collection is being supported by a generous gift from The Rockefeller Foundation.

The collection consists of 4,500 photographs documenting natural environments, ecologies, and plant communities in the United States at the end of the nineteenth and the beginning of the twentieth century. Produced between 1891 and 1936, these photographs provide an overview of important representative natural landscapes across the nation. They demonstrate the character of a wide range of American topography, its forestation, aridity, shifting coastal dune complexes, and watercourses.

Major topics and issues illustrated include the establishment of the Everglades National Park; the growth of the modern conservation movement and its institutions, including the National Audubon Society; the evolving role of women on the political stage; the treatment of Native Americans; rights of individual citizens or private corporations vs. the public interest; and accountability of government as trustees of public resources, whether for the purposes of development, reclamation, or environmental protection. The materials in this online compilation are drawn from sixteen physical collections housed in the archives and special collections of the University of Miami, Florida International University and the Historical Museum of Southern Florida.

The Printed Ephemera collection at the Library of Congress is a rich repository of Americana. While the broadside format represents the bulk of the collection, there are a significant number of leaflets and some pamphlets. Rich in variety, the collection includes proclamations, advertisements, blank forms, programs, election tickets, catalogs, clippings, timetables, and menus. They capture the everyday activities of ordinary people who participated in the events of nation-building and experienced the growth of the nation from the American Revolution through the Industrial Revolution up to present day.
