{{Tl|Citation needed}} (also known by the redirects {{Tl|Cn}} and {{Tl|Fact}}) is a [[Wikipedia:Template messages|template]] used to identify questionable claims that lack citation to a reliable source. The template produces a superscripted notation like the following:

:Humphrey Bogart has won several snooker world championships.{{Citation needed|date={{CURRENTMONTHNAME}} {{CURRENTYEAR}}}}.
While Humphrey Bogart ''may'' have played snooker at some point and ''may'' have won a tournament at one time, there is no ''reliable'', ''published'' source to verify this. Also it is not common knowledge.

== TemplateData ==
<templatedata>
{
	"description": "",
	"params": {
		"name": {},
		"reason": {},
		"date": {
			"autovalue": "{{subst:CURRENTMONTHNAME}} {{subst:CURRENTYEAR}}",
			"suggested": true
		}
	}
}
</templatedata>

==Usage==

'''Notes''':
* [[Help:Substitution|Substitution]] of this template will automatically fill the date parameter.
* If you don't add a date parameter, a [[Wikipedia:Bots|bot]] 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) {{para|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.":
:<code>{{Tlx|Citation needed|reason{{=}}This claim needs a reliable source; Bogart was a famous actor, and his major biographies don't mention snooker.}}</code>

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

===Examples===

:<code>This sentence shows the template used at the end.{{Tlx|Citation needed|reason{{=}}reliable source needed for the whole sentence}}</code>

''The above wikitext will render as follows:''

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

The template should be inserted ''after'' punctuation, such as a period or comma.
<!--
:<code>While this example{{Tlx|Citation needed|2=1=shows the template}} used to request a citation for a specific part of a sentence.</code>

''The above wikitext will render as follows:''

While this example {{Citation needed|1=shows the template}} used to request a citation for a specific part of a sentence.

===When not to use this template===

The <nowiki>{{Citation needed}}</nowiki> 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 [[Template:Cn#Inline_templates|list of inline templates]]. For example, claims that you think are incorrect should be tagged with {{Tl|Dubious}}. 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.

=== 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.  

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.
