This category is used for administration of the Wikipedia project, and is not part of the encyclopedia. It contains pages which are not articles, or groups articles by status, rather than content.
Articles in category contain statements that may become dated originating from September 2008. The statements may need to be updated, removed or edited for perspective. Articles containing older statements are more likely to be dated. This is not a backlog; not all articles in this category will need updating at this point in time.
Use {{As of}} to mark all individual statements that may become dated, this will automatically add them to the appropriate categories. Wherever possible, use {{Update after}} to mark exactly when statements will need updating in addition to using {{As of}}.
