[citation (source) needed]

[edit] [purge] Template-info.svg Template documentation

(This is derived from the Wikipedia version of the same template and this document needs a re write to clean up references to wikipedia documents and Tractor Wiki versions creating to replace them

This template can be used in articles to identify sentences or short passages which need an inline citation. It produces a superscripted notation like the following:

Humphrey Bogart is the greatest actor that ever lived.[citation (source) needed]

Use this template to "tag" information which may be questionable, so that other editors can know to back up the statement with citations, per Wikipedia:Verifiability.

You can also add "dummy" parameters to leave a better record for future editors. For example, the following usage might be appropriate to the arguable claim that "Humphrey Bogart is the greatest actor...":

{{fact|please give a reliable source for this assertion. How about Laurence Olivier?}}

Adding this template to an article places the article into one of a family of categories identifying "Articles with unsourced statements". To find all such articles, see Category:All articles with unsourced statements.

When not to use this template

Material which is doubtful and harmful may be removed immediately, rather than tagged. See Unsourced material.

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.

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.

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

Alternative names

Some find the name "fact" is unclear or non mnemonic, not referring to citations explicitly, so you can use {{Citation needed}} or {{Cn}}. These redirect to {{Fact}}, they are alternate names for the same template. Cleanup bots will often replace redirected templates, so {{Citation needed}} and {{Cn}} will often get changed to {{Fact}}.
