• This category ishidden on itsmember pages—unless the correspondinguser preference (Appearance → Show hidden categories) is set.
• These categories can be used to track, build and organize lists of pages needing "attentionen masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
• These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

This category combines all articles that aremissing citations for specific statements, tagged since the given month (or before), from February 2010(2010-02) to enable us to work through the backlog more systematically. It is a member ofCategory:Articles with unsourced statements.
Adding{{Fact}} after an unsourced statement will add the article to this category. Use{{Citations missing}} for articles that cite some sources, but insufficiently.

Please use{{Unreferenced}} for articles that do not cite any sources at all. SeeCategory:Articles lacking sources for pages that have no identified source material.
