Template:Citation needed/doc

Citation needed is a template used to identify claims in articles, particularly if questionable, that need a citation to a reliable source. This template produces the superscripted message and is installed with no spaces directly after punctuation.

Example 1
This sentence shows the template used at the end.

This wikitext will be rendered as follows:


 * This sentence shows the template used at the end.

Example 2

 * Humphrey Bogart was an avid snooker player.

The template indicates that it may be that Humphrey Bogart played snooker at some point and it may be that he was enthusiastic about the game but no reliable, published sources were given to verify it and the information is not considered common knowledge.


 * Humphrey Bogart was an avid snooker player.

Example 3
If it is considered that he might have played snooker but was not an avid player, a reason for the need of a citation may be given, displayed as a tooltip when the mouse hovers on "citation needed":


 * Humphrey Bogart was an avid snooker player.


 * Humphrey Bogart was an avid snooker player.

In this example, it may be better to use the Citation needed span, which has slightly different syntax, template to highlight the word "avid".

When not to use this template
Contentious material about living persons that is unsourced or poorly sourced should be removed immediately. Do not tag it; immediately remove it. This includes material that is disparaging, misrepresentative, insulting, harmful, or possibly libelous. For some policy about this, see the sections "Remove contentious material that is unsourced or poorly sourced" at Biographies of living persons and "Burden of evidence" at Verifiability.

The 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 Dubious, and those which represent a non-neutral view should be tagged with POV statement. Being specific about the nature of the problem will help other editors correct it.

Within a lead section that is clearly written as a summary of a substantially sourced article,
 * statements that are supported with citations within the body of the article should not be tagged,
 * statements that are not supported in the article body should be tagged with Not verified in body.

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 requires neither reliable sources for common well-known facts (e.g., "the Moon orbits the Earth"), nor 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 WP:MINREF for the list of material that is absolutely required to be followed by an inline citation, rather than a general reference or no citation at all. Also note that the burden of evidence lies with the editor who adds or restores material.

This template is intended for specific passages that need citation. For entire articles or sections that contain significant material lacking citations (rather than just specific short passages), there are other, more appropriate templates, such as Unreferenced and More citations needed (for whole articles) as well as Unreferenced section and More citations needed section (for sections of articles).

Do not use this template to tag policies or guidelines.

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 contentious claims about living people, which should be immediately removed if not cited, there is no specific deadline for providing citations. Please do not delete information that you believe is correct solely because no one has provided a citation within an arbitrary time limit. If there is some uncertainty about its accuracy, most editors are willing to wait at least a month to see whether a citation can be provided.
