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.

This is a tracking category for all CS1 citations that use |url= without an associated |title=.

|<param>= missing title

All Citation Style 1 and Citation Style 2 templates report this error when one of the URL-containing parameters cannot be paired with an associated title. This error may also occur when |title= cannot be linked with |url= because the citation also contains a conflicting |title-link= parameter.

URL-containing parameters and associated title parameters

URL parameters	Title parameters
|archive-url=	|title=
|article-url=	|article=, |chapter=, |contribution=, |entry=, |section=
|chapter-url=	|chapter=, |article=, |contribution=, |entry=, |section=
|conference-url=	|conference=, |event=
|contribution-url=	|contribution=, |chapter=, |article=, |entry=, |section=
|entry-url=	|entry=, |chapter=, |article=, |contribution=, |section=
|event-url=	|event=, |conference=
|map-url=	|map=
|section-url=	|section=, |chapter=, |article=, |contribution=, |entry=
|transcript-url=	|transcript=
|url=	|title=

A unique case exists for {{cite journal}}: if |pmc= or |doi= has a value, |url= is omitted or empty, and |title-link= does not point to an article, then |title= is automatically linked with the same URL as the PMC or DOI. This default behaviour can be overridden using |title-link=none/pmc/doi.

Because URLs are ugly and generally uninformative, it is expected that editors should provide a meaningful title for each URL. In most cases this can be accomplished by using the |title= parameter.

To resolve this error, provide an appropriate title for the URL-containing parameter. In the case where |url= and |title-link= are contending for |title= you must choose which one to keep. Consider moving |url= or |title-link= to a more suitable parameter.

Pages with this error are automatically placed in Category:CS1 errors: bare URL.^[a]
