Category:CS1 errors: missing periodical

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).

This category is used by Module:Citation/CS1/Configuration for categorization.

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 tracking category for CS1 periodical citations that do not have a periodical parameter.

Cite <template> requires |<param>=

This error message is hidden. To show this error message see Controlling error message display.

These CS1 periodical templates require a periodical parameter. The periodical templates are:

{{cite journal}}

{{cite magazine}}

The error message suggests a periodical parameter that matches the template, but there is no requirement to use the suggested parameter; any one of these periodical parameters may be used:

• |journal=
• |magazine=
• |newspaper=
• |periodical=
• |website=
• |work=

In some cases, an incorrect template has been used (e.g. {{cite journal}} for a web page, book, or standalone document). The appropriate resolution in these cases is to change the incorrect template to {{cite web}}, {{cite book}}, or a different, more appropriate template.
