Category:Pages with authority control identifiers red-linked category

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

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:Pages with authority control identifiers (respectively Module:Pages with authority control identifiers). 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).

This error-tracking category is used to catch any categories with red-linked categories being assigned via {{Pages with authority control identifiers}}. The most likely cause is that a new parameter/ID has recently been added to Module:Authority control, and the editor has created the initial set of 4 tracking categories, but has yet to create their parent(s).

Categories in this category should only be added by {{Pages with authority control identifiers}}.
