This is a tracking category.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. It is not part of the encyclopedia's categorization scheme.
This is the top-level tracking category for the various CS1 citation error, status, maintenance, and development categories. This category should not contain individual pages. Pages in the individual subcategories should only be added by CS1 templates and Module:Citation/CS1.
