This is page providing resources that editors can use to create articles about properties and districts listed on the U.S. National Register of Historic Places. Resources of national scope are given first, then by-state-and-territory reports of what resources are available, followed by useful resources for maintenance and other purposes. Also of interest is WP:NRHPMOS, a Style Guide guideline to be followed when creating articles under the scope of this project, and WP:NRHPFAQ, a list of frequently asked questions about the project.

Resources of national scope[edit]

NRIS[edit]

The NRHP stores information about sites listed on the Register in a database known as the National Register Information System (NRIS). There are several web resources which in effect are front-ends for querying this database, although the database also can be downloaded in its entirety from this National Park Service website, which several of our members have done. One member, User:Elkman, has downloaded the database and hosts it on his personal website so that project members can query the database without having to download it. The most commonly used tool on Elkman's site is the Infobox Creator, commonly known as the "Elkman NRHP infobox generator," which parses the database information into a detailed pre-fabricated NRHP infobox that can be used in new articles. To use the infobox generator, search for the name or reference number of the desired site. You can then cut-and-paste the infobox (and other useful information such as categories and talk page material) into an article.

Note: There is a consensus throughout the project not to create very short stubs with only bare NRIS data, especially not when full NRHP nomination documents or other sources are available online for the listing in question and could easily be added to the article. It is desirable to at least include a paragraph or two in new articles explaining why the site is listed on the NRHP and/or any other major details, if you can ascertain such. Almost all NRHP-listed places are Wikipedia-notable topics, so a new editor should not be discouraged from starting an article even if online resources are sparse. Feel free to ask for help further developing any of your articles at the project talk page.

Although the NRIS is generally treated as a reliable source for information about sites listed on the Register, any database of its size undoubtedly contains errors, many of which have been found and sorted out by project members on this page (although many of those found have not yet been corrected in the database itself). There are occasional entry errors in the database and/or in the front-end used to query the database. These errors have appeared in listing/delisting dates, official names, locations, and other fields. Also, being a database rather than a written source, even the information provided without error is very limited. The NRIS does not distinguish between architects, contractors/builders, and engineers; frequently gives incomplete lists of architectural styles present in a listing; and gives dates which are not properly interpreted by some front-ends (e.g. NRIS identifies some as "circa" rather than definite dates and sometimes provides multiple relevant dates which may include a date of a significant event other than the built date).

The data given by the NRIS or interpreted by front-ends is not necessarily wrong, but it is often incomplete. As such, the project strongly recommends including multiple sources in new (and existing) articles to verify/clarify the NRIS data. Any input error (except coordinate errors) found in NRIS data given by the Elkman generator or other means should be reported on this page under the appropriate heading. These reports are collected and forwarded to the NPS periodically.

NPS Focus[edit]

The NRHP's "NPS Focus" system is a front end to query NRIS data which is provided by the NPS. In addition to providing data from NRIS, links to NRHP application documents in PDF format are included. The system will always show clickable links for the document and accompanying photo set for the place, whether or not those are actually available online. Clicking the links will often download a PDF file that merely states "The PDF file for this National Register record has not yet been digitized," in which case the documents are not available online (although they may still be available from a state-level resource). In this case, the document can be requested from the NRHP directly. See below for instructions on how to request these documents.

The Focus search interface can be found here. To find information about a listing, simply go to the Focus site, type in the official NRHP name, select a geographic region if desired, and click Search. The site will return a list of NRHP listings from which you can select the appropriate link. According to an NPS Focus status report page, Focus contains a "skeletal record" for all properties listed in or before August 2012. All properties listed after then can be found in the weekly announcement listings.

NRHP nomination forms[edit]

Official National Register of Historic Places nomination documents are available in some form for all listings. It is highly recommended that every NRHP article use the official NRHP Inventory/Nomination document as a source about the listing. They often include primary research information including description of the condition of a property at the time the document was written and secondary research information about the historical importance of the place. They are provided by the Federal government but are often written by state or local government staff or by private consultants or other parties who have not transferred copyright. As such, they are generally not in the public domain, even though most U.S. Federal government works are. Unless they are prepared by Federal staff workers, the copyright is believed to be held by the author of the document. If they are public domain, you might include text from these documents directly without paraphrasing, but it is desirable in either case to summarize them and paraphrase for better article quality. The NRHP wikiproject generally treats public domain texts exactly like any other sources, except that quotes from them may be longer than would represent "fair use" of copyrighted material. It is always helpful to provide a link to public domain materials that are available on the web, either as an external link or as an explicit reference, just as it is helpful to link to copyright-protected materials. The NRHP nomination documents include information about the historical significance of a property, a brief description of the property, and can sometimes even include pictures or maps.

Almost all NRHP nomination documents and accompanying pictures are in the Focus database for Multiple Property Submissions (see Wikipedia:WikiProject National Register of Historic Places/MPS cover sheets), National Historic Landmarks, and sites owned by the National Park Service, as well as for sites listed in the following states as of August 2013, according to this Focus status page):

  Almost all nominations online at NPS Focus
  Almost all nominations online at state-level or other source
  Almost all nominations online, but require payment
  Some nominations online at state-level or other source

Nomination forms that the NPS Focus system asserts "have not yet been digitized" may or may not be available in electronic form from the NPS or state-level resources. All nomination forms are available upon request from the NPS, either in electronic form by email or in photocopied form to be sent through the U.S. postal service. To obtain these documents, you can send an email to nr_reference@nps.gov, or you can send a letter to the following address:

National Register of Historic Places

National Park Service
1201 I St. NW
8th Floor (MS 2280)

Washington, DC 20005

In the email or letter, include the name of the property, county, state, NRHP reference number (if available), and the name of the Thematic Resource, Multiple Resource Area, or Multiple Property Submission (if applicable). There is a limit of two paper copies per request, but there is no such limit on email.

NHL Summaries[edit]

The National Park Services NHL search site provides access to a webpage summary for every NHL site, including for archaeological sites where the NRHP text is not made available. This summary page includes a short statement of significance of site based on the NRHP text. The NHL webpage sometimes also includes current and past status information for sites that are threatened. This NHL webpage summary is usually authoritative on the official NHL name for the site, which may differ from the official NRHP listing name for the site shown in the NRIS system. When an NRHP site is also a NHL, the NHL name takes precedence in the title of the NRHP infobox of an article and usually the title of the article as well. This summary page is usually authoritative on the date of NHL designation, which should be added into the NRHP infobox of the article.

While these webpages and documents are usually accurate, some errors have been found in fields as critical as the reference number of the site, the site's name, and the site's NHL designation date. Some of the errors have been reported to the National Park Service and are under review. A working list of known or apparent errors with names of sites appears here. Any errors you find should be reported at that article as well.

Some National Park Service webpages include photos that are NPS-owned and are public domain. But the NPS is clear that it uses, with permission, some copyrighted pictures, and those do not go into the public domain just because the NPS uses them. The National Park Service copyright-related policy statement, at http://www.nps.gov/disclaimer.htm states, under Ownership:

"Information presented on this website, unless otherwise indicated, is considered in the public domain. It may be distributed or copied as is permitted by the law. Not all information on this website has been created or is owned by the NPS. If you wish to use any non-NPS material, you must seek permission directly from the owning (or holding) sources."

Until late 2009 or early 2010, there was an ERRONEOUS message in the NPS Focus computer system that states "Public domain" for all photographs, whether they are or not. That has since been changed to show "Public access". Any photo that gives credit to a photographer, a state employee, or any other non-Federal organization is not in the public domain and thus cannot be used on Wikipedia without consent from the photographer. It is up to users, not the NPS, to check for copyright status of any photos. Any photo that is listed as being from the "National Register Collection", however, is believed to be owned by the NPS and thus in the public domain. Only images in the public domain (or another accepted license Click here for more information) may be added to articles. Any other images will be removed. The table to the right includes several sources that may contain public domain images about NRHP listings.

To avoid any copyright problems, you may simply take photos yourself if you live or travel in the area of a property listed on the NRHP or request that other editors take pictures if they come in contact with them. If you or any other editor takes the photograph, the photographer has exclusive rights to the copyright status of the photograph and must release it into the public domain or under an acceptable license in order to use it in a Wikipedia articles.

It is also possible that the images you need already exist on Wikipedia's partner site Wikimedia Commons. You can look through Commons:Category:National Register of Historic Places or categories specific to the state or region in which the NRHP listing is located to find useful images.

Courthouse photos[edit]

The United States Department of Agriculture has a collection of 328 courthouse photographs taken by Calvin Beale. The Federal Judicial Center has nearly six hundred photographs of historic federal courthouses.

Other resources[edit]

NRHP.COM

National Register of Historic Places.COM is a private website mirroring the NRHP's NRIS database. It gives listings by state and division within state (counties, parishes, etc.). This is often referred to by the project as "NRHP.COM". It is known to contain systematic errors, however, such as giving areas of historic districts that are 10x larger than correct and including an erroneous listing date for properties that have actually been de-listed on that date. It is not recommended for use in Wikipedia citations, but can be a handy source for a site's reference number or other info.

Historic Places Database

Another private source of information, also mostly a mirror to the NRIS database, is Historic Places Database. It may give listing as well as delisting dates.

Weekly announcement listings

Every Friday, the National Park Service publishes a new weekly list outlining all actions on the National Register for the prior week(s), including additions, removals, boundary increases and decreases, additional documentation, approvals of multiple property submissions (MPS), determinations of eligibility, and designations of NHLs. The weekly list (and all previous lists) can be found here. Since July 2008, the weekly update has included one featured property, listed here.

If the listing date for the property is not known, a quick way to find it is to Google the name of the property and append "site:www.nps.gov". For example, when looking for information on Beth Hamedrash Hagadol, search Google for "Beth Hamedrash Hagadol" site:www.nps.gov, which turns up the relevant weekly announcement. For older NRHP listings (pre-1995), the announcements are in pdf format and thus not searchable. For these properties, you will have to manually search through the yearly listings.

Note: a real advantage of such searches is that they can turn up announcements of additional documentation packages provided for a site. Just searching NRIS and NPS Focus will not reveal the availability of these. To obtain them, you may have to request the additional documentation from the National Register directly. The additional documentation might or might not also appear in the PDF files for the site that might be available via the NPS Focus system.

National Park Service Inventory

The National Park Service has an inventory of historic park structures with pictures at List of Classified Structures.

GSA database

Multiple resources regarding historic federal government buildings under General Services Administration management may be found at Historic Buildings, which can be searched and sorted by state, architect, and other attributes.

HABS and HAER

The Historic American Buildings Survey and the Historic American Engineering Record provide photos and sometimes substantial text records for many sites that are NRHPs.

State and territory specific resources[edit]

As stated above, there are several states in which all of the NRHP nomination documents are available through the Focus database. Although many states are not included in this list, there are state-level databases that include the documents, as well as other helpful information. The NRHP website includes this list of links to state and territory specific State Historic Preservations Offices (SHPOs). Other tools are listed below. Click on the desired state in the following index table to jump straight to available tools for that state. States in bold have almost all nomination documents in Focus (although there may still be a link to other resources).

  • This search site provides a lot of information. Louisiana documents about NRHP places are searchable here and include links to PDF summaries, photos, and maps. The PDF summaries may be multiple page documents which may be based upon, or basis for, the NRHP nomination documents of the properties. However, these summaries omit author, date, and other information that would improve them as citable references, so obtaining the full NRHP nomination documents from the National Register is still recommended.

Maine
  • The Maine Historical Preservation Commission website contains a list of properties "recently added" to the register. There is also an archive which lists sites listed after about 2005. The site contains only short summaries, no nomination documents.
  • Every Maine municipality is required to periodically produce a comprehensive master plan for the municipality. These documents often list the community's historic properties, and may provide more detailed addresses (and sometimes alternate names and current usage details) than are available from the NRHP. They should be available through the municipality's web site.

  • NRHP nomination documents available online for almost all listings; see #NPS Focus above.
  • An index linking to concise site summaries may be found at the Nebraska State Historical Society. It shows 10 regions for the state's 93 counties. One level higher is this NRHP general menu. Full NRHP nomination documents are available for some counties. The Nebraska State Historical Society may provide NRHP documents for other sites if contacted directly.
  • Photos in Nebraska are more commonly available than in most other states, in already existing Commons categories of photos corresponding to many individual NRHP listings, even where there is not yet an individual wikipedia article (mostly courtesy of commons/wikipedia contributor Ammodramus - thanks!). Be sure to browse within Commons:Category:National Register of Historic Places in Nebraska by county to find these, and consider adding an External link such as "More photos of the Dry Valley church and cemetery at Wikimedia Commons", as included in the Dry Valley Church and Cemetery NRHP article.

New York
  • The New York State Office of Parks, Recreation and Historic Preservation (NYSOPRHP) provides scanned versions of the NRHP text documents, NRHP photos, and NRHP correspondence with owners of properties. The interface requires Java on your computer. In the New York's State and National Registers of Historic Places Document Imaging Project search access screen, you have to select "Basic" and enter Basic criteria such as name "Grahamsville" and county "Sullivan" in the search form, and then click over on the right at RESULTS to get the search to run. Not entirely intuitive. It may be then that a Java icon shows up for a while, and then you typically get a list of the 3 documents available (text, photos, other). Then clicking on one of them, in Firefox at least, you get a new browser window with a wide but short scrollable window showing about one vertical inch of the scanned document. You can then choose to click on the printer icon and print to a PDF file, in order to save it on your computer and to read it more conveniently. (If you do not already have a PDF writer on your computer, you can download a free one at www.pdf995.com). The new browser window shows a hard URL that can be used to provide a hard link from a Wikipedia article to a specific file, such as Grahamsville Historic District NRHP text for the article Grahamsville Historic District. An example footnote reference linking the separate text, photos, and correspondence documents for one site, is as follows:
Formatting of documents available at New York State's OPRHP

Documents available at NYS OPRHP may be footnoted as here, for example: In 1992 the vessel was listed on the National Register of Historic Places.[1]

  • A state-wide 1999 listing of NRHP places, the Ohio Historic Places Dictionary should be consulted and referenced if you get access to information on a given NRHP. Organized by county, then alphabetical. Preview access is seemingly randomized, so you might or might not get to the page you need; as well, some sites listed before 1999 are omitted without explanation, including a large chunk in the "L" counties.

  • NRHP nomination documents available online for almost all listings; see #NPS Focus above. Note: The Oregon Historic Sites Database described below provides superior response time, uptime, and query tools to the NPS Focus database.
  • The Oregon Historic Sites Database has been completed, and includes links to scanned NRHP nomination documents (PDF format) for most listings. Most notably, nomination documents for "address restricted" listings have been systematically excluded, although database records for those listings are present. The database also includes records for a large number of historic properties that are not listed on the national register, as well as individual records for historic district contributing properties. Scanned PDF documents from other (non-NRHP) historic surveys are also present for many records.
  • Full PDF nomination documents/photos and HTML summaries for the most recent listings in the state are here — in principle this page covers the most recent 6 months, though this time span varies with the availability of SHPO staff time to maintain the page. The HTML summaries can be useful editorial guides, but care should be taken in using them as citations in articles: after the listings are cycled off the page, the HTML summaries are no longer generally available. When citing the PDF nomination documents by URL, use the URL from either NPS Focus or the Oregon Historic Sites Database rather than the URL used on the recent nominations page; similar to the HTML summaries, the recent nominations URL becomes invalid after the listing is cycled off the page.

Pennsylvania
  • The Cultural Resources Geographic Information System (CRGIS), which replaced the ARCH database, provides scanned copies of NRHP documents. Large amounts of data are available with the guest password and account provided by the site. To use the system at all seems to require that you install an Adobe SVG (Scalable Vector Graphics) Viewer software on your computer. If/when it is working for you, the fastest way to find sites in the CRGIS system is to use the "Ask REGIS" feature to either search by county, name, architect, historic function, etc. In at least some cases such as for Northumberland Historic District, the scanning is incomplete (deliberately?).

Step-by-step tips for using CRGIS:

  1. Use Microsoft Internet Explorer (not Mozilla Firefox) as browser.
  2. Go to start screen at https://www.dot7.state.pa.us/ce/SelectWelcome.asp
  3. Scroll down to "To get started, click on the CRGIS logo". Click on it.
  4. At "CRGIS Welcome and Login" page, note the instructions are to use "Public" and "Public" as userid and password. Note also that it notes "Microsoft Internet Explorer 5.5 or greater is required", that "An ActiveX control is used to build maps. Click here to see if you have it installed on your machine", that "It is recommended that your screen resolution be set to 1024 x 768 or better" and that "Popup boxes are extensively used on this site. Your browser MUST be configured to accept popup boxes for CRGIS to be able to function." Click on "Login".
  5. It may be that nothing happens. Going back one step and checking on the ActiveX control may reveal that ActiveX is not installed on your PC, but you may be given no directions where you can get it. (Can any other editor help improve the instructions here? At what URL could one try to get the needed ActiveX control? )
  6. You may be confronted with a message requesting that a page be closed, which you may just say No to.
  7. In the login process, give "Public" and "Public" as userid and password where needed. Accept terms for use.
  8. In the "Cultural Resources GIS" page in a new window that pops up, scroll down to "Ask REGis" button. Click on it.
  9. In yet another new popup window, you may search for specific properties. You could select "Where?" or "When?" to find properties by county or otherwise, but probably selecting "What else?" works quickest for finding a given place. In the screen that pops up, select "Historic name" from the pulldown menu and enter part of the name of the place, so it will implement a search on "where historic name includes" namepart. You can use the second field to specify only NRHP sites (useful as the CRGIS system also includes most Eligible-but-not-listed and also Ineligible buildings) by clicking "National Register Status" and then clicking "Listed".
  10. When finished, click "Search Now" and results should appear. Clicking or double-clicking on a result will bring up another popup where the link to the nomination form, as well other relevant documents, can be found. (Note, selecting individual entries by using the checkbox, and then selecting "Map Selected" above will bring up a map, but will not bring you to the documents.) For example, the results window for "Bailey Covered Bridge" in Washington County, Pennsylvania provides a link to NR form "H050859_01H.pdf".
  11. Click on the NR form link, to bring up an Adobe Acrobat window showing the PDF document. The URL of the specific document appears and can be used in Wikipedia references.

Formatting of references for documents that were available at Pennsylvania's ARCH system

For Cogan House Covered Bridge, its ARCH footnote includes an accessdate but note the NRHP document it includes is itself undated (because no date appears in the document),[1]

For Worlds End State Park, the ARCH footnote includes a Pennsylvania doc rather than one on NRHP form, and there is a document date.[2]

For Millersburg Ferry, the ARCH footnote includes 3 PDF files (one NRHP text and two accompanying maps).[3]

Tennessee
  • The state's Department of Environment and Conservation (parent agency of the Tennessee Historic Commission) provides NRHP documents for at least some NRHP sites on-line. The Historic Commission's main NRHP page has some listings, and others are listed in press releases, for example these 12 recent ones here, nine more recent ones here, this list from December 2008, and this search results screen. The Historic Commission seems to abandon its old content when new content is added, but old content can be found on old versions of http://tennessee.gov/environment/hist/federal/nrhist1.shtml saved at archive.org.
  • Middle Tennessee State University's Center for Historic Preservation, which did the research for many of the state's NRHP nominations, has posted a lot of research material and many nominations on the web under the title "Southern Places", at this link. Search on words on the property name, or search on the place name or county name. Topics particularly likely to be included are African American Churches, Cemeteries, Farms, Houses, Railroad Stations, Rosenwald Schools and other Schools, Trail of Tears, and Women (e.g., Woman's Club). The main MTSU library search page http://digital.mtsu.edu/cdm/ will sometimes return additional relevant material.
  • Information about properties in Rutherford County is available in a 2005 newsletter of the county historical society.
  • Also there is a "Tennessee Encyclopedia on History and Culture" on-line, search here sponsored by the Tennessee Historical Society, which has articles that may be useful as references and/or external links.

  • Data has been found on the Texas Historical Commission's FTP server ftp://ftp.thc.state.tx.us. Most NRHP registration forms are listed in the /nr_program/ directory.
  • Summary information and perhaps the text from the NRHP documents (but incomplete, clearly lacking sections), is available for NRHPs in the Texas Historical Commission's THC Atlas system.
  • The Handbook of Texas [12] provides summaries and some detailed histories of historic sites. Note in citing Handbook of Texas, most articles have individual authors to credit; the Fort Concho Wikipedia article contains an example footnote reference giving such credit.

Virginia
  • NRHP nomination PDFs and other materials are available, by county and independent city, for most all (but not archeological site ones) at the Virginia Landmarks Registry here. These often include a full NRHP nomination document, a webpage of accompanying photos, and sometimes a webpage with one or more maps. All their sites are listed in their Register Master List, which is useful sometimes for establishing which city or county an archeological site is located in, for sure.

Copy-paste and adapt:

<ref name=nrhpdocVAdhr>{{cite web|url=__ |title=National Register of Historic Places Inventory/Nomination: __ |author=__ |date=__ |publisher=Virginia Department of Historic Resources}} and [__ accompanying photos] and [__ accompanying map]</ref>

Washington
  • NRHP nomination documents available online for almost all listings; see #NPS Focus above.
  • The WISAARD GIS system provides a database, including PDFs of nominations. It only works with Internet Explorer and requires that pop-ups be enabled. The map interface is clunky and requires a lot of zooming; it works if you're patient and have some idea of Washington geography and the site you're looking for.

Coordinates issues[edit]

North American Datum shift between NAD27 and NAD83

Coordinates returned by the NRIS may not always be spot on. In many cases, coordinates of NRHP listings were traced out on old U.S. Geological Survey quadrant maps which still followed the North American Datum of 1927. In 1983 there was a world-wide adjustment of all geographic coordinates, to the current system used now by all current geolocation and maps providers. This shift changed coordinates in a majority of the U.S.; only the area near Chicago was unchanged. Older NRHP listings' coordinates are more than likely a bit off, with the error increasing the farther one travels from Chicago. Newer nominations are more often be more accurate.

While many coordinates issues can be traced to the above shift, there are sometimes outright typos or other errors in coordinates that appear in NRIS. Coordinates for historic districts or plantations or other large properties are often at a calculated geocenter of the corner points of the area, when pointing to the main plantation house may be more desirable. The project welcomes corrections of NRIS coordinates, but our members do not actively collect reports of these issues. All other errors in NRIS data should be brought up here.

These links may help you identify correct coordinates to include into the infobox:

  • 1a. If a street address is available, use Google maps to bring up a satellite view of the property.
  • 1b. Or use this UTM coordinates converter to latitude&longitude to get approximate location based on UTM info in the NRHP registration document. Enter degrees-minutes-seconds coordinates into infobox fields and save article. Then bring the Google satellite view up by clicking on those coordinates in this article.
  • 2. In another window, bring up Geolocator tool, useful to zero in on exact building in its satellite view. Having the Google map satellite view in other window helps you find the location. Follow geolocator's instructions to alt-click and get exact coordinates.
  • 3. Revise the article's coordinates to the geolocator's more precise coordinates.

Tools and other useful links[edit]

Other useful links include:

  • National Historic Landmarks Program - list of National Historic Landmarks
  • National Register of Historic Places home page
  • National Register of Historic Places.COM - a private website echoing the NRHP's NRIS database, giving listings by state and division within state (counties, parishes, etc.). This is often referred to as "NRHP.COM". It is known to contain systematic errors, due to its programmer(s) not understanding some important nuances of the NRIS database. For example, it gives areas of historic districts that are 10x larger than correct. For another example, it includes as NRHP-listed on a given date, places that were in fact de-listed on that date. It also includes a few locations that were never approved and are still marked "Pending/listed."
