Category:Pages using citations with format and no URL

From Wikipedia, the free encyclopedia

This is a tracking category for CS1 citations that use |format= without also providing a url for |url=. For media format, instead use |type=.

  • |format= requires |url= (error message hidden by default)
  • |...-format= requires |...-url= (error message hidden by default)

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 (e.g. PDF, DOC, XLS, etc.). In some cases an editor may have intended to use |type= to specify a kind of document (e.g. hard cover, paperback, pamphlet, etc.) The |format= and |...-format= value is always displayed.

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

|archive-format=, |chapter-format=, |conference-format=, |contribution-format=, |event-format=, |lay-format=, |section-format=, |transcript-format=

As of 29 November 2014, |chapter-format= is a new parameter. Citations that relied on the old, somewhat odd use of |url= and |format= may need adjustment.

To resolve this error, remove |format= or |chapter-format=; define |url= or |chapter-url=; or change |format= to |type= (or to |chapter-format= if |chapter-url= is used without |url=.

Pages with this error are automatically placed in Category:Pages using citations with format and no URL.[a]

While most of the Citation Style 1 and Citation Style 2 error messages are visible to all readers, some remain hidden. Editors who wish to see all of the CS1|2 error messages can do so by updating their common or skin CSS stylesheet to include:

.citation-comment {display: inline !important;} /* show all 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 WP:NULLEDIT will resolve that issue.
