Category:CS1 errors: contributor

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).
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 CS1 and CS2 templates that cite a secondary author's contribution to a book.

|contributor= ignored

Only used in book citations, |contributor= identifies the author of a contribution, typically an afterword, foreword, introduction, preface, etc., to another (primary) author's work. This error occurs when |contributor= is used in a template that is not {{cite book}} or {{citation}} or is one of these two templates and one of the |work= parameter aliases is set.

To resolve this error, consider the |others= parameter, choose a more appropriate CS1 or CS2 template or remove |contributor=.

Pages with this error are automatically placed in Category:CS1 errors: contributor.

Help desk

|contributor= requires |author=
|contributor= requires |contribution=

Only used in book citations, |contributor= identifies the author of a contribution, typically an afterword, foreword, introduction, preface, etc., to another (primary) author's work. As such, the primary author is required (|author= or appropriate alias) as is the title of the contribution (|contribution=).

Pages with this error are automatically placed in Category:CS1 errors: contributor.
