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. More information: This category is hidden on its member pages—unless the corresponding user preference is set. 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). Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see Special:TrackingCategories for an overview of the latter).

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

This is a tracking category for CS1 citations that use the parameter |language= to identify non-English language sources. For an article to be categorized in a subcategory of this category, the value assigned to |language= must have a MediaWiki-supported 2-character language tag, 2-character based IETF-like language tags, or the language name associated with those tags; multiple tags/names are supported an article may appear in multiple subcategories. This category should not contain individual articles. Articles in the subcategories should only be added to them by CS1 templates using Module:Citation/CS1. Subcategories in this category are ordered by language tag.
