About National Register Documentation:

Since its inception in 1966, more than 92,000 properties have been listed in the National Register. Together these records hold information on more than 1.4 million individual resources--buildings, sites, districts, structures, and objects--and therefore provide a link to the country's heritage at the national, state, and local levels.

The Documentation consists of

  • National Register registration form, which provides a physical description of the place, information about its history and significance, and a bibliography.
  • Photographs - Use of photographs and forms is available under Fair Use, see our Content and Copyright page for more information
  • Maps
Many State Historic Preservation Offices (SHPOs) have digitized their files and put them on their websites. The depth of information available varies from state to state, but ranges from basic locational information to searchable databases with downloadable narrative descriptions and photos. You can check their websites to see if they have the information you need. List of SHPOs with extended information.
