History of The National Register of Historic Places - Reorganization

Reorganization

In 1973 the NPS history programs affiliated with both the U.S. National Parks system and the National Register were formally categorized into two "Assistant Directorates." Established were the Assistant Directorate for Archeology and Historic Preservation (ADAHP) and the Assistant Directorate for Park Historic Preservation (ADPHP). The Assistant Directorate for Archeology and Historic Preservation dealt with those cultural resources which were external to the National Parks system. The ADAHP included the Grants, National Register, Historical and Architectural Surveys and the Interagency Services Divisions of the Park Service. The ADPHP, on the other hand, dealt primarily with those resources associated internally with the NPS. The ADPHP included the History, Archeology and Historic Architecture Division.
