all Wikipedia Articles In Need Of Updating

This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

This category includes all pages marked as being outdated by {{Update}}. Because of its size, users may prefer to work with Category:Wikipedia articles in need of updating, which subdivides reference requests based on when they were requested. This category exists primarily as an aid to bots and other automated processes.
