National Register Database and Research

The National Register of Historic Places is the official list of the Nation's historic places worthy of preservation. Authorized by the National Historic Preservation Act of 1966, the National Park Service's National Register of Historic Places is part of a national program to coordinate and support public and private efforts to identify, evaluate, and protect America's historic and archeological resources.

How to Find our Files

  1. National Archives (NARA): Holds our records up to the end of 2012.
    The National Archives is the permanent home of our records and everything will eventually be in the National Archives.

    How to search NARA's holdings.
    The easiest way is to look up the property in the searchable table below or download our spreadsheet. Both contain direct links to the files that have been scanned.

    Reference number search:
    If you know the reference number or found it in the searchable table below or from our spreadsheet then follow this link to NARA and just replace the reference number with the one you want or the property name.

    Name search: You can also do a name search. Follow this link to NARA and replace the name of the property.

    Search by state:
    Use the finding aids for each state and territory in the National Archives Catalog. Select your state and click on “Search Within this File Unit.”

    Search by Keyword:
    Each individual file has text recognition. In addition NARA's search engine will allow you to search across all pdfs for instances of the word/phrase. Sample searches: Rachel Carson, Trail of Tears, Bridges in Texas

  2. National Register of Historic Places NPGallery Database:
    Some files that are not on NARA's website are in NPGallery. Properties listed since 2013 are being posted to NPGallery.

  3. If the file has not been posted online yet you can request a copy from us. Please include the name of the property, the state, and the reference number (or as much information as you know on the property). And e-mail the request to us at: Reference e-mail

Restricted files have not been posted online.

Common Searches:

You can download our spreadsheet and look by state, county, city, or street address. You can also search for addresses in our map. The map contains some anomalies (especially with complex historic districts). These problems are due to the way in which we collected data. We have done work on fixing our data and continue to do so. For more information see our Data Downloads page
You can use the spreadsheet of NHLs to find the name and reference number for each National Historic Landmark. Then you can search by reference number at NARA. Or search the NPGallery Database and select National Historic Landmark System as the "Record Category"
You can use the MPS spreadsheet to find the name and reference number for each cover. Then you can search by reference number at NARA. Or search the NPGallery Database and select National Register Multiples (covers) as the "Record Category"

About National Register Documentation:

Since its inception in 1966, more than 95,000 properties that Americans believe are worthy of preservation 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.
