Category:Authors with approximate birth dates

• sister projects: Wikidata item

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 approximate birth dates. The birthyear parameter has been entered with, for example, "circa Y", a decade or even a century. This may be because the precise birth date has been lost or because it was simply unknown at time of editing. It is possible that further research will lead to the discovery of the precise year of birth which, when entered into the author template on the author page, will remove the author from this category.
