Index provides a brief description of all national parks.
Organized by state, sites of historical significance are noted. A fold-out map, the National Park System Map and Guide , lists activities and facilities for visitors at over 300 parks, monuments, and historic sites. NPS Handbooks, more detailed introductions to natural and historic places administered by the NPS, provide informative reading on specific National Historic Landmarks located within the park system. Some NPS publications can be obtained by visiting a NPS site. All can be purchased by mail from the Superintendent of Documents, Government Printing Office.
