Category:CS1 maint: multiple names: authors list

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 hidden tracking category for CS1 citations that use |author=, or its aliases where Module: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=, their aliases, and enumerated equivalents (e.g. |author2=, |last2=, 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 of post-nominals: |author=FC White, RN, MD, Ph.D. To fix these errors in citations:

1. Remove post-nominals.
2. Provide enumerated author parameters (e.g. either |author2= or |last2= and |first2=) for each author of a cited work.
3. When multiple separator characters are legitimately present in a name (commonly a corporate, institutional, or governmental author), the name may be wrapped in two sets of parentheses (or <nowiki>...</nowiki> tags) to suppress assignment to this category, like this: |author=((Federal Ministry of Transport, Building, and Urban Development)) or |author=<nowiki>Federal Ministry of Transport, Building, and Urban Development</nowiki>.

Editors should not simply replace |author= with |authors=. Using the plural |authors= parameter to replace a singular |author= or |last= parameter that holds multiple authors' names is discouraged because automatically decoding lists of human names is an extraordinarily difficult task. Because of this difficulty, names listed in |authors= are omitted from the template's COinS metadata. Enumerating the author list with |authorn=, or |lastn= / |firstn=, or, where appropriate, |vauthors=, preserves the associated metadata. Pages in this category should only be added by Module:Citation/CS1. Pages with this condition are automatically placed in Category:CS1 maint: multiple names: authors list.^{[lower-alpha 1]}
