Category:Authors with non-numeric birth dates
This is a maintenance category, added by a template to group pages for maintenance (non-navigation) purposes. It is automatically hidden on categorized pages.
These authors have non-numeric birth dates entered into the "birthyear" parameter of the author template. These are more complicated to handle but may also be sorted into more specific subcategories.
