It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. They are not part of the encyclopedia's categorization scheme.
These categories are 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 even if it is empty! This category may be empty occasionally or even most of the time.
If this category has 1000 items or more, it will report as a backlog. (recount)
This is a tracking category for CS1 citations that use the bot-specific parameter value |dead-url=bot: unknown. The keyword bot: unknown is intended for use by bots to identify original urls that are alive but not confirmed to link to appropriate material. Editors should review these urls and adjust the value assigned to |dead-url= accordingly. Pages in this category should only be added by Module:Citation/CS1.
