Here are the latest reliable summaries about Heritage Documentation Programs (HDP) based on recent public updates and official sources.
Core HDP overview
- The Heritage Documentation Programs comprise three main initiatives under the National Park Service: HABS (Historic American Buildings Survey), HAER (Historic American Engineering Record), and HALS (Historic American Landscapes Survey). Documentation created through these programs is archived in the Library of Congress and is publicly accessible. This remains the core mission of HDP, documenting built environments across the U.S. for preservation, education, and research.[2]
Recent signals and activities
- Official HDP pages emphasize ongoing documentation of America’s built environment and continued public accessibility of the collection. The NPS notes that HABS/HAER/HALS documentation is archived at the Library of Congress and is publicly accessible, underscoring a stable, ongoing preservation mission.[2]
- HDP project highlights are periodically featured by NPS, illustrating concrete documentation efforts, case studies, and partnerships at regional scales. You can review project highlights to see representative recent activities and outcomes.[9]
- Educational and outreach content, including webinars and public-facing materials, continues to promote HDP methods and the value of documentation for preservation planning, interpretation, and access. For example, webinars cover tools, case studies, and standards development around HDP practices.[3]
