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.




National Register of Historic Places Focus Database

We have not yet digitized the following states: Arkansas, Illinois, Massachusetts, Michigan, Missouri, North Carolina, New York, Pennsylvania, Ohio, Texas, and Virginia.

If the file has not been digitized 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 

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. Records listed from 1966-2012 that have been scanned are in the NRHP Focus Database. Records from 2013 to the present are in our weekly list search page. We will scan all of our records and put them into one source. We recognize and apologize for this inconvenience.


The three spreadsheets are current through late September of 2015.  While not all nominations have been digitized yet, we provide PDF links for the text and photos for those that have been digitized in our collection which can be reached by clicking on the text or photo spreadsheet cell.  We have not yet digitized the following states: Arkansas, Illinois, Massachusetts, Michigan, Missouri, North Carolina, New York, Pennsylvania, Ohio, Texas, and Virginia.  If you cannot follow a link to the documentation on a property it is because we have not digitized it yet or it is a “restricted” archeological site.

The sort order is by state, county and resource name or, in the case of multiples, by state and resource name.  Standard spreadsheet navigation tools allow you to go to “Find and Select” in the upper right hand corner of the spreadsheet and using the find utility you can search for keywords such as “Fort”. The default search searches all columns but you can restrict a search to a given column by highlighting the column.  For example you can search for properties in Fairfax County, Virginia by highlighting the County column and searching for Fairfax. 

Additional resources on our site you can use, particularly for finding copies of recent nominations, can be found at

Many times individual states offer additional digitized information, which can be found at

Almost two million pages of the PDF text and photos are word searchable in the Advanced Search in Google by going to and limiting the site or domain to the Focus server, and entering your search parameters.

About National Register Documentation:

Since its inception in 1966, more than 90,000 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 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.
