Category:CS1 errors: missing periodical

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

Help desk

This is a tracking category.

It is used to build and maintain a list or 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 (Appearance → Show hidden categories) 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 subcategories 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.

Cite <template> requires |<param>=

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}}, {{cite document}}, or a different, more appropriate template.
