The National Park Service Maritime Heritage Program is dedicated to advancing awareness of the role of maritime affairs in the history of the United States. The Maritime Heritage Program Web site provides detailed information about their substantial preservation programs, including indices of historic ships (searchable by state), lighthouses, and life-saving stations within the United States and its territories. Along with these databases, another prime highlight of the site are the online publications located here. Perhaps most helpful for persons interested in historic preservation, they include the Historic Lighthouse Preservation Handbook (released first in 1997) and the Guidelines for Historic Vessel Preservation Projects. For persons with a penchant for maritime history and preservation, this site will be a welcome addition and provide helpful information about visiting and locating some of these historic sites.
