Category:Pages using citations with format and no URL

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).

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 citations that use |format= without also providing a url for |url=. For media format, instead use |type=.

Help desk

|format= requires |url=
|...-format= requires |...-url=

These errors occur when Citation Style 1 and Citation Style 2 templates use |format= or |...-format= without also providing a corresponding URL for |url= or |...-url=, respectively. The |format= and |...-format= parameters are used to specify the file format of a web resource, such as PDF, DOC, or XLS. In some cases an editor may have intended to use |type= to specify a kind of document, such as hard cover, paperback, or pamphlet. The |format= and |...-format= value is always displayed.

The list of |...-format= parameters is:

(Citations that relied on the pre-2014, somewhat odd use of |url= and |format= may need adjustment in regard to |chapter-format=.)

Pages with this error are automatically placed in Category:CS1 errors: format without URL (0 pages).^[a]

By default, Citation Style 1 and Citation Style 2 error messages are visible to all readers and maintenance category messages are hidden from all readers.

To display maintenance messages, include the following text in your common CSS page or your specific skin's CSS page (common.css and skin.css respectively):

.mw-parser-output span.cs1-maint {display: inline;} /* display Citation Style 1 maintenance messages */

To display hidden-by-default error messages:

.mw-parser-output span.cs1-hidden-error {display: inline;} /* display hidden Citation Style 1 error messages */

Even with this CSS installed, older pages in Wikipedia's cache may not have been updated to show these error messages even though the page is listed in one of the tracking categories. A null edit will resolve that issue.

To hide normally-displayed error messages:

.mw-parser-output span.cs1-visible-error {display: none;} /* hide Citation Style 1 error messages */

You can personalize the display of these messages (such as changing the color), but you will need to ask someone who knows CSS or at WP:Simple talk if you do not understand how.
