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.




We are currently scanning our records. Unfortunately, until they are all scanned, they will be in 3 different places.

1. National Register of Historic Places NPGallery Database
However, the database does not include files for the states of: Arkansas, Illinois, Massachusetts, Michigan, Missouri, North Carolina, New York, Pennsylvania, Ohio, Texas, and Virginia.

Sometimes the pdf shows up as "gibberish". We are looking into this, but we think it has to do with the browser Chrome and Safari and how they "view" the pdf. If this occurs, please download the pdf, you may have to hit the download option in the browser, then open it.

2. National Archives. All of our records will eventually be in the National Archives. Right now NARA has the states of: Arkansas, Illinois, Michigan, North Carolina, Rhode Island, Texas, and Virginia. (and more will be added.)

How to search NARA's holdings. The easiest way is if you know the reference number. (Available on our spreadsheet. Then follow this link to NARA And just replace the reference number with the one you want, or the property name.

3. Weekly List Search Engine for new listings (from 2013 to the present)

4.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 

Restricted files have not been posted online.


You can see a map and do an address search of non-restricted listed properties in the National Register of Historic Places at:

The map prefers Google Chrome, and doesn't work well in Firefox or Internet Explorer.

To download GIS spatial data, please see the instructions on our Data Downloads page.


The three spreadsheets are current through late September of 2015. 

Listed properties on the National Register (over 90,000)

Spreadsheet of NRHP Listed Properties

National Historic Landmarks

Spreadsheet of NHLs

Multiple Cover Documents in the National Register

Spreadsheet of Multiple Property Covers (up to 2015, includes links to pdfs and breakdown by states)

Spreadsheet of Multiple Property Covers (up to 2018, does not include links to pdfs or breakdown by states)

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. 


More spreadsheets on our Data Downloads page.

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

Searching text through multiple pdfs:

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 NPGallery server,

and entering your search parameters.

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.


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.
