This is a hidden tracking category forCS1 citations that use|author=, or its aliases whereModule:Citation/CS1 identifies cs1|2 citation templates that appear to use singular forms of author name-list parameters to list multiple authors' names. Doing so corrupts the citation's metadata.
The citation module code looks for multiple comma or semicolon separator characters in the value assigned to|author=,|last=,|first=, their aliases, and enumerated equivalents (e.g.|author2=,|last2=,|first2=, etc.). This test displays an error message for multiple authors' names in a single parameter, as well as single author names that include a comma-separated list ofpost-nominals (|author=FC White, RN, MD, Ph.D) and comma-separated generational and regnal suffixes (|first=John F., Jr).
To fix these errors in citations:
|author2= or|last2= and|first2=) for each author of a cited work.|author=((Federal Ministry of Transport, Building, and Urban Development)).Pages in this category should only be added byModule:Citation/CS1.
Pages with this condition are automatically placed in Category:CS1 maint: multiple names: authors list.[a]
By default,Citation Style 1 andCitation Style 2error messages are visible to all readers andmaintenance messages are hidden from all readers.
To displaymaintenance messages in the rendered article, include the following text in your commonCSS page (common.css) or your specific skin's CSS page and (skin.css).
(Note to new editors: those CSS pages are specific to you, and control your view of pages, by adding to your user account'sCSS code. If you have not yet created such a page, then clicking one of the.css links above will yield a page that starts "Wikipedia does not have auser page with this exact name." Click the "Start the User:username/filename page" link, paste the text below, save the page, follow the instructions at the bottom of the new page on bypassing your browser's cache, and finally, in order to see the previously hidden maintenance messages, refresh the page you were editing earlier.)
:root.mw-parser-output.cs1-maint{display:inline;}/* display Citation Style 1 maintenance messages */
To display hidden-by-defaulterror messages:
:root.mw-parser-output.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. Anull edit will resolve that issue.
After (error and/maintenance) messages are displayed, it might still not be easy to find them in a large article with a lot of citations. Messages can then be found by searching (with Ctrl-F) for "(help)" or "cs1".
To hide normally-displayederror messages:
:root.mw-parser-output.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 atthe technical village pump if you do not understand how.
Nota bene: these CSS rules are not obeyed byNavigation popups. They also do not hide script warning messages in the Preview box that begin with "This is only a preview; your changes have not yet been saved".
