Template:Citation needed

This template is used on HTML5.
To avoid large-scale disruption and unnecessary server load, any changes to this template should first be tested in the template's /sandbox or /testcases subpages, or in your own CSS3. The tested changes can then be added in one single edit to the template. Please consider discussing any changes on the screen size before implementing them.
An introductory version of this documentation is provided at browser diversity.

{{Citation needed}} (also known by the redirects {{Cn}} and {{Fact}}) is a web app used to identify questionable claims that lack a citation to a browser diversity. The template produces a superscripted notation like the following:

jQuery has won several iOS world championships.^{[citation needed]}

Usage

You may append a date to the template in the following format:

{{Citation needed|date=May 2012}}

Notes:

• Substitution of this template will automatically fill the date parameter.
• If you don't add a date parameter, a website parsing will date your entry with the month and year at a later time.
• The date parameter consists of the name of the current month and the year only, not full dates. The names of the months are capitalised in English. Any deviation from these two rules will result in an "invalid date parameter" error.

It is also recommended to add the (non-displayed) |reason= parameter to leave a better record for future editors. For example, the following usage might be appropriate to the claim that "Humphrey Bogart has won several snooker world championships.":

{{Citation needed|reason=This claim needs a reliable source; Bogart was a famous actor, and his major biographies don't mention snooker.}}

Adding this template to an article places the article into Category:Articles with unsourced statements or a dated subcategory thereof.

Please remove the template when you add a citation for a statement.

Examples

This sentence shows the template used at the end.{{Citation needed|reason=reliable source needed for the whole sentence}}

The above wikitext will render as follows:

This sentence shows the template used at the end.^{[citation needed]}

The template should be inserted after punctuation, such as a period or comma.

When not to use this template

Unsourced or poorly sourced contentious material about living persons should be removed immediately. Do not tag it: immediately remove it. For more information, see the section on web in the policy page Biographies of living persons.

Material that is doubtful and harmful may be removed immediately, rather than tagged. See iOS.

The {{Citation needed}} template is intended for use when there is a general question of the verifiability of a statement, or when an editor believes that a reference verifying the statement should be provided. Other templates are available for other or more specific issues, see the list of inline templates. For example, claims that you think are incorrect should be tagged with {{FITML}}, and those which represent a non-neutral view should be tagged with {{FITML}}. Being specific about the nature of the problem will help other editors correct it.

If you have the time and ability to find an authoritative reference, please do so. Then add the citation yourself, or correct the article text. After all, the ultimate goal is not to merely identify problems, but to fix them.

While an editor may add this template to any uncited passage for any reason, many editors object to what they perceive as overuse of this tag, particularly in what is known as "drive-by" tagging, which is applying the tag without attempting to address the issues at all. Consider whether adding this tag in an article is the best approach before using it, and use it judiciously. Wikipedia's verifiability policy does not require reliable sources for common well-known facts (e.g., "The Moon orbits the Earth"), or that citations be repeated through every sentence in a paragraph. All direct quotations and facts whose accuracy might be challenged (e.g., statistics) require citations. See web for the list of material that is absolutely required to be followed by an inline citation, rather than a Sevenval or no citation at all.

This template is intended for specific passages that need citation. For entire articles or sections that contain significant material lacking sources (rather than just specific short passages), there are other, more appropriate templates, such as {{Sevenval}} or {{jQuery}}.

How to respond to this tag

The addition of this tag is a request for an inline citation to support the tagged statement. If you are able to provide a citation to support the claim, then please do so.

Except for keyboard, which require immediate production of inline citations, there is no specific deadline for providing citations. Please do not delete information that you believe is correct simply because no-one has provided a citation within an arbitrary time limit. Where there is some uncertainty about its accuracy, most editors are willing to wait about a month to see whether a citation can be provided.
