National Register of Historic Places Program: 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.



Status of our collection:

We are currently digitizing our records. This has led us to splitting the collection into two parts:
1966-2012 and 2013-present.


Research Properties listed from 1966-2012 in 2 ways:

• Our Database (Focus) - which contains many digitized records.
click here to see what properties (by state) in Focus have been digitized

(We have been having issues with our database of late, if it is down, please let us know by e-mailing us.)

• Download spreadsheets of listed, removed, Federal DOEs, and more properties.


Research Properties listed from
2013-2014 (fully digitized)

• 2013-2014 Weekly List Search Engine


Geographical (GIS) Data

• Now available from our Data_Download page


How to best find:

Multiple Property Covers:
Most MPS Covers have been scanned: use the MPS spreadsheet to find the reference number, then use the advanced search feature in Focus to search by reference number.

National Historic Landmark Files:
NHL properties are automatically listed in the National Register of Historic Places. Most NHL files have been scanned and are in Focus. The NHL website has a page that gives helpful tips on finding the NHL file in Focus. This page on the NHL website

National Park Service Properties:
Most NPS Properties have been scanned and are in Focus. You can search by Park name.

If an address is listed:
You can do an address search in the spreadsheet and in the weekly list search engine (for new properties). Many properties are within historic districts. You can look for likely districts based on the address field in the spreadsheet. You can also try looking at the GIS data we have.

Determinations of Eligibility:
DOEs have not been scanned. You can download a spreadsheet of Federal DOEs.

A little search trick with our database. For the files that are scanned, the url is the same except for the reference number at the end. So if you know the reference number (available from our spreadsheets) then you can go directly to the pdf.

Many State Historic Preservation Offices (SHPOs) have digitized their files and put them online. 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 extended information.
