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 tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme. Pages are added to this category by Template:Authority control (respectively Module:Authority control). This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set. These categories can be used to track, build and organize lists of pages needing "attention en 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).

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

This tracking category includes articles and categories which transclude ((Authority control)) with explicit parameters. Pages are sorted by namespace. Please move all IDs to Wikidata.

Pages in this category should only be added by Template:Authority control.
