Category:CS1 maint: PMC format

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 (except for eponymous maintenance 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.

This category tracks CS1 citations that use |pmc= where the assigned value contains a pmc (case insensitive) prefix.

• 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).

Many (although not all) cases in the category can automatically be fixed by clicking here to activate User:Citation bot.

This is a tracking category for CS1 citations that use |pmc= where the assigned value contains a pmc (case insensitive) prefix. Historically, cs1|2 templates using |pmc= used only the identifier number. The prefix may be removed. Pages in this category should only be added by Module:Citation/CS1.

Pages with this condition are automatically placed in Lua error in Module:Citation/CS1/Configuration at line 2172: attempt to index field '?' (a nil value)..^[a]
