This template is a special case of {{One source}}, used for when the single source cited by the article is the National Register Information System (NRIS), through the use of {{NRISref}}. The rationale is that this source is known to be somewhat error-prone, despite its official status as a database maintained by the United States National Park Service.

The template is usually added automatically by User:NationalRegisterBot, but it can also be added manually. It is added by the bot when the only inline citations in the article or section are to the NRIS database. The bot will remove the template if it is present on articles with inline citations to other sources.

{{NRIS only|date=November 2024}}

{{NRIS only|section|date=November 2024}}

The first unnamed parameter replaces "This article relies" with "This PARAMETER relies".

For example, "{{NRIS only|section}}" would display:

This section lacks inline citations besides NRIS, a database which provides minimal and sometimes ambiguous information. Please help ensure the accuracy of the information in this section by providing inline citations to additional reliable sources. (Learn how and when to remove this message)

As with most cleanup templates, the date= parameter sorts the article into subcategories of Category:Articles sourced only to NRIS, allowing the oldest problems to be identified and dealt with first. You do not need to specify the date manually since a bot will add it later automatically; nonetheless adding the date is encouraged.

This template should only be used for articles which include only inline citations to the NRIS via {{NRISref}}. The bot will tag articles even if other non-inline sources are listed in a "References" section.

Please consider improving the article or making a good faith attempt to locate additional sources and creating additional inline citations before adding this template.

If this template is removed from an article without improving said article, the bot will automatically re-add the template until the problem is fixed. If you believe the bot is doing this in error, direct all questions to User talk:NationalRegisterBot.

• {{Failed verification}} — Citation does not support the article's claim(s)

This template will categorise tagged articles into Category:Articles sourced only to NRIS. If a date is supplied, a monthly category like Category:Articles sourced only to NRIS from November 2024 will be used instead.
