Jump to navigation Jump to search

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]


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.

Although the NRIS is generally treated as a reliable source for information about sites listed on the Register, it, like any database of its size contains errors, many of which have been found and sorted out by project members on a set of "corrections needed" pages (which hopefully may someday be corrected in the database itself). There are occasional errors of several types: data entry errors in the database, original errors in the NRHP nomination documents from which the NRIS data is taken, extraction/presentation errors 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. For example NRIS does not distinguish between architects, contractors/builders, and engineers; it 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, while one popular front end does not convey those distinctions).

The NRHP wikiproject 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. It is intended that these reports will be collected and forwarded to the NPS periodically.

NPS Focus, now NP Gallery[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.

To use, go to the NPGallery search interface It may be referred to by its soft redirect "shortcut" wp:NPSfocus or wp:NPGallery. To find information about a listing, simply go to the Focus search 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. In the past, according to an NPS Focus status report page, Focus contained 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.

Individual Wikipedia articles for NRHP properties and articles containing lists of properties will often include a clickable reference number that will open the NP Gallery listing for that property, including the summary information and links to the nomination form and associated photos, for example: (#09000817) or NRHP Reference # 09000817.

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 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

The map included to the right shows the availability of nomination files in the Focus database as well as in state-level resources. Most properties listed before September 2014 are available in the Focus database, except for those in the states listed below, according to [ this page (as of 1/2017). Most of their listing forms are available via the National Archives Catalog described below.

In addition, almost all NRHP nomination documents and accompanying pictures are in the Focus database for Multiple Property Submissions (more info here), National Historic Landmarks, and sites owned by the National Park Service. Sites that are listed as "Address restricted" (mainly archaeological sites) are not available in Focus due to sensitive location information but can be obtained according to the directions below, albeit with the location information redacted from the nomination copy.

Even if a nomination form is not available in Focus (and even if Focus reports that the form is "not yet digitized"), the NPS nonetheless will usually have a digital copy that they have not yet added to the database, and they will surely have a hard copy. These are available upon request from the NPS by email at If the NPS does not have a digital form to send by email, a paper copy can be sent through the U.S. postal service. To obtain these documents, simply include your home address in the email, 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. If the site in question is address restricted, location information will be redacted from the form for security reasons.

National Archives Catalog[edit]

Via a cumbersome interface the National Archives and Records Administration provides scanned and OCR'd NRHP nomination documents for a growing number of states. These may be viewed online and downloaded to your own computer.

To use:

  • Usually the following should work, because usually you will have the NRHP reference number for the property (e.g. from the county list-article of NRHP listings): at National Archives Catalog, enter the refnum into searchbox at upper left, then click the search icon (a magnifying class image) just to its right. Results should include the NRHP document, click on that, bringing up a screen with a viewer box that seems like it should include the document, but probably is blank. What happens next is probably dependent on your browser, your computer/internet speed, and other factors. The viewer eventually should work, but you might have to leave it running for 10 minutes or so, with no indicator of progress going on. Alternatively, without waiting, you can download the document to your computer: click on the "download" icon (with a down-arrow in its image) below the userbox. Using Chrome browser on a reasonably new PC in 1/2017, this works okay, with progress in terms of cumulative MB downloaded being reported (though no total filesize or percentage progress shows).
  • Alternatively, you can try searching for a given NRHP property name (or fragment thereof), but depending on the uniqueness of the name there may be too many results to be useful.
  • If you don't have the NRHP reference number, you can still follow a process which reliably should get the desired document or establish that it is not available. To do so, search the relevant state-specific "finding aids". Using the Texas database as an example, jump to this starting point: National Register of Historic Places and National Historic Landmarks Program Records: Texas (NAID 37250329). For a regular NRHP listing, find the "Texas Single Property Listings Finding Aid" document by scrolling down and click on that. It brings up a viewer window, which fairly promptly should show the finding aid document. In the viewer window-specific search (click on the magnifying glass icon within the viewer window) enter the NRHP property name and step through occurrences until you find it and its reference number. Then type the reference number into the main search box at upper left, and then hit the "search" icon. If the property is a National Historic Landmark, scroll to find the "Texas National Historic Landmarks Finding Aid" instead, and search within that. Multiple Property Submissions are listed in another finding aid document.

States for which listings appear to be completely available, excepting listings with restricted addresses (as of July 2018):

To reference the NRHP document you have found, you need a permalink to the document, which is by use of the "National Archives Identifier" for the property. This is a different number than the NRHP reference number. E.g. for Muskegon Historic District, having reference number 72000647, the archives identifier is 25340169. You can see this number in the results from searching by the refnum. The NRHP document for that property is at permalink A model reference for cut-and-paste usage is:
<ref name=nrhpdoc>{{cite web|url= |title=National Register of Historic Places Registration: |publisher=National Archives |author= |date= | accessdate=August 10, 2018 }} ({{NationalArchivesNote}})</ref>

[Note 1: The above sample reference uses a template, {{NationalArchivesNote}}, to provide a message that currently displays "Downloading may be slow.

" This message may be updated centrally and will revise what is displayed in all such references. The note seems helpful for readers, to warn them of oddly big filesize and/or oddly long downloading time.]

[Note 2: A number of references based on the NRHP document, when believing that permalinks to the National Archives versions were not available, were created by me (doncram) and perhaps other editors, using the following cut-and-paste-able model:
<ref name=nrhpdoc>{{cite web|url= |title=National Register of Historic Places Registration: |publisher=National Archives |author= |date= | accessdate=August 10, 2018 }} (accessible by searching within [ National Archives Catalog])</ref>
These should probably be searched out and replaced by permalinks. --doncram 17:54, 8 May 2017 (UTC)]

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 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]


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 "". For example, when looking for information on Beth Hamedrash Hagadol, search Google for "Beth Hamedrash Hagadol", 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.


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

Buildings of The United States

Published by the Society of Architectural Historians [12] through the Oxford University Press, the series is a long-term project to document American architecture on a state-by-state basis in a manner similar to Nikolaus Pevsner's The Buildings of England. The following volumes have been published as of mid-2017:

  • Alaska (1993), Colorado (1997), Delaware (2008), District of Columbia (1993), Hawaii (2011), Iowa (1993),Lousiana (2003), Massachusetts (Boston) (2009), Michigan (r.2012), Nevada (2000), North Dakota (2015), Pennsylvania (Philadelphia and eastern PA) (2010), Pennsylvania (Pittsburgh and western PA) (2010), Pittsburgh (2007), Rhode Island (2004), Savannah (2016), Texas (south, central, Gulf coast) (2013), Vermont (2014), Virginia (Tidewater and Piedmont) (2002), Virginia (Valley, Piedmont, Southside and Southwest) (2015), West Virginia (2004) and (Wisconsin (2017) Arkansas is expected in late 2017.

The older versions are available for under $10.00 used.

State and territory specific resources[edit]

As stated above, there are many U.S. states in which almost all of the NRHP nomination documents are available through the Focus database. Also for some states 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.

New York[edit]

  • The New York State Office of Parks, Recreation and Historic Preservation (NYSOPRHP) formerly provided scanned versions of the NRHP text documents, NRHP photos, and NRHP correspondence with owners of properties via the New York's State and National Registers of Historic Places Document Imaging Database. In February 2015, the NYSOPRHP launched the GIS based Cultural Resource Information System (NY-CRIS) which replaces the previous online resources. CRIS is a robust Geographic Information System program that provides access to New York State's vast historic and cultural resource databases and now digitized paper records including National Register of Historic Places Inventory/Nomination Forms. User can access to more than 1.5 million pages of digital images including, National Register documents, building and archaeological inventory forms and survey reports and a wide variety of additional legacy data. In addition, the new system serves as an interactive portal for agencies, municipalities and others who use historic preservation programs, such as the State and Federal Income Tax Credits for Historic Properties, the State and National Registers of Historic Places Programs, the Sections 14.09 (NYSPRHPL) and 106 (NHPA) review processes, the Certified Local Government Program and building and archaeological survey programs.

Once in CRIS, National Register forms can be retrieved as follows:

  1. On the main page, click on Search
  2. Under the search Criteria tab, click on the National Register subtab
  3. Search for the Listing Name (note: NR Number in CRIS does not match the NPS NR number)
  4. Click on View (the magnifying glass) for the interested site
  5. With the specific site returned (National Register Project Details), click on the Atts. tab
  6. One of the attachments will be the scanned Nomination Form, click on the download icon to view the form
Issues with CRIS citations

User:pubdog confirmed with OPRHP the following when inquiring about a cross-reference for National Register information between the old and new portals:

From, February 17, 2015

I consulted with other OPRHP staff, and they were unaware of the Document Imaging links used for NRHP listings on Wikipedia. Apparently, these were added to Wikipedia by people outside of OPRHP. We do not have plans to edit or maintain these links; however, other people are welcome to do so at their discretion. The URL format in your example (with the ViewDoc query) is probably the best way to link the files, though I am not aware of any plans to use these as permanent links [example used was for Kibler High School.
If you have further questions, please let us know!
Matthew W. Shepherd, MLIS
Digital Archive Program Assistant
New York State Parks, Recreation & Historic Preservation

Therefore, users adding new citations or revising existing links should be aware that links to NRHP forms in NY-CRIS may not be persistent. I tried pulling up forms in Firefox, Internet Explorer (IE), and Chrome. In IE and Chrome, I was able to get a specific link to the registration form and photos; in Firefox I could not get the link to display.

With this, I propose the following citation to NRHP forms and photographs in the CRIS:

<ref name="NysNrhpNom">
{{cite web
| url =
| title = "Cultural Resource Information System (CRIS)"
| publisher = [[New York State Office of Parks, Recreation and Historic Preservation]]
| format = Searchable database
| accessdate = 2015-11-01
}} ''Note:'' This includes 
{{cite web 
| url =
| title = National Register of Historic Places Registration Form: Central Avenue Historic District
| accessdate = 2015-11-01
| author = Hannah Beckman and Jennifer Walkowski
| format = PDF
| date=June 2014}}
 and [ ''Accompanying photographs'']</ref>

With the professed lack of persistent URLs there is a risk involved. Therefore, users may also need to access the NRHP registration form by searching CRIS. Depending on their purpose, they may want to become a registered user.

  • 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. See usage in Harshaville Covered Bridge. Copy-paste and adapt (change at least the page number) the following reference:

<ref name=OHPD>{{cite web|url= |title=Ohio Historic Places Dictionary, Volume 2 |date=1999 |publisher=Somerset Publishers, Inc.|editor=Lorrie K. Owen |page=3}}</ref>

  • The Ohio History Connection (formerly the Ohio Historical Society) provides very basic data (usually little or nothing more than the NRIS) and often a picture. Nomination forms in PDF are available, but a small price must be paid. Search for item at or add the NRHP reference number at the end of the following url:

  • NRHP nomination documents available online for almost all listings; see #NPS Focus above.
  • The National Archives Catalog has most nomination forms here (NAID 76018483).
  • 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.

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
  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.
  12. To do another search, you have to click the "Search For" tab (the browser's "Back" button doesn't work here).
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]

  • 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. Such materials may be referenced by copy-pasting and adapting:

<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>

  • The National Archives Catalog has most nomination forms here (NAID 40571316).
  • It has been noted wt:NRHP that "recent Virginia nominations are typically available from the DHR web site, but are not always obviously locatable by navigation of the site. They seem to be published as part of the agendas for SHPO-related meetings. If you want to see the nomination for a recent listing, search Google using keywords from the name, restricting the search to" However, it was further noted that "The problem is that they actively take down those ones after a while."

  • NRHP nomination documents available online for almost all listings; see #NPS Focus above.
  • The National Archives Catalog has most nomination forms here (NAID 74615694).
  • The WISAARD GIS system provides a database, including PDFs of nominations. It only works with Internet Explorer and requires that pop-ups be enabled. Use full-screen display to ensure you can see the search field at top left in map and resource interfaces. The map interface (default) is clunky and requires a lot of zooming (Q: but how do you zoom at all?); it works if you're patient and have some idea of Washington geography and the site you're looking for. Selecting "Resource" instead of "Map" allows you to search more normally: hovering cursor over "Resource" opens a smallish window with a "Go to resource" search field open at the bottom. Enter the property name there. At the resulting page on the given property, click on "Documents and images" at the left, which brings up the first image available. Scroll down to see thumbnails of other images and possibly a PDF icon for a National Register registration document. To open the document, you have to click in the top right part of it (where hovering displays "Click to open full size attachment". The document, once brought up, has a permanent url which can be referenced from outside the system and using other browsers. So, for example, a reference for use in an NRHP article like the following can be constructed: <ref name=nrhpdoc>{{cite web |url=|title=National Register of Historic Places Registration: First Methodist Episcopal Church / First United Methodist Church / Daniels Hall|publisher=Washington State|accessdate=August 10, 2018|author=Katheryn H. Krafft |date=July 2010}} (includes 40 photos)</ref>.

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. Zero in on exact building in satellite view. Right-click, then select "What's here?". Copy-paste coordinates shown.
  • 3. Revise the article's coordinates to the geolocator's more precise coordinates.

Tools to install[edit]

You can change how your Wikipedia account works in some ways by changing your user preferences (click on "Preferences", which will be at your upper right if your account uses the default "Vector" appearance/"skin"). There are a couple files which control how your account works with javascripts, however, that are separate. These depend on your vector.js file and/or your common.js file. These files may be found if you go to your userpage and click on "Subpages" (at left, under "Tools") and scroll to the end. Hmm, maybe "Subpages" is a tool itself which depends upon your having the following line in your commons.js file:

mw.util.addPortletLink ('p-tb', wgServer+wgArticlePath.replace("$1", "Special:PrefixIndex/"+wgPageName+"/"), 'Subpages');

Well, for another way to see your common.js file you can just go to User:USERNAME/common.js (but change "USERNAME" to your own username). Or you can get to it via "preferences" (see below under "Measuring Tool"). To see the other, go to User:USERNAME/vector.js (but change "USERNAME} to your own username).

Per Wikipedia:Village pump (technical)/Archive 152#common.js vs vector.js, it doesn't matter where they are if you always use the vector appearance/skin. But scripts which work in any appearance/skin can be put into your common.js file. Scripts which work only in the vector skin are best put into the vector.js file.

NRHP stats reading[edit]

To get access to yellow boxes which show "NRHP Progress" stats, add the following lines to the end of your vector.js file:

var NRHPstatsAuto = 'false'; // per wt:NRHPPROGRESS#Untagged articles, line 1 of 2
importScript('User:Dudemanfellabra/NRHPstats.js'); // per wt:NRHPPROGRESS#Untagged articles, line 2 of 2

The tool works reliably when using Microsoft Edge browser but not in Chrome browser. See discussion at wt:NRHPPROGRESS.

Measuring tool[edit]

(adapted from Wikipedia:WikiProject North America/The North America Destubathon)

You can check size of articles using this tool To do so you would program the common.js in your preferences to contain:

importScript('User:Dr_pda/prosesize.js');                // User:Dr pda/prosesize


  1. Go into your preferences, and click the "appearance" tab;
  2. Where it says "Shared CSS/JavaScript for all skins:", click "custom javascript" (this brings you to your common.js file)
  3. Paste the command given above into that and save.
  4. Now approach an article and look in the tools section on the left. You should see "Page size". Click that for each article and you'll quickly get a reading without having to paste text all of the time and look externally.
  5. Look out for where it says, for example: "Prose size (text only): 1684 B (289 words) "readable prose size" ".

Tools and other useful links[edit]

When scrolling in a long table, keep headers in view[edit]

Preferences -> Gadgets -> Testing and Development -> Make sure that headers of tables remain in view as long as the table is in view (Requires Safari or Chrome).

Editing tables[edit]

  • For adjusting sortable tables, e.g. to sort numbers mixed with number ranges properly, see Help:Sorting. There are now sort types which can be defined for columns, easier than inserting a sorting code in each row, which can work well in some cases.
  • An easy-to-use online wiki table editor is at
  • To renumber the rows, after inserting or deleting an entry, in the long NRHP list-tables, there's a tool in the NRHPupdater system. (Explanation how to use it is needed, here.)


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."
