Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time. Populated by {{Lifetime needed}}.

This category contains items which have been identified as lacking information on the lifetimes of their authors, illustrators or contributors of the works concerned, which is ideally needed to help confirm the public domain status of the works concerned.

Items should be removed from this category when:

1. All the relevant authors, illustrators or contributors (which can be) identified are detailed, and appropriate information on their lifespans exists.
2. It is clear that the work was first published in the US, or is clearly of US origin, and that the copyright therein has expired.
   Such as it being published prior to 1929, or a work in which copyright wasn't renewed, or applied.
3. The work was first published prior to 1874.
   Nearly all works published prior to this date can with a few specific exceptions be reasonably considered public domain.
   If these exceptions are likely to apply, or despite this date authors (or lifespans) have been identified that would make the work still subject to copyright then please raise the issue at COM:VPC on a case by case basis.
4. The work can be confirmed to have originated with a governmental entity (other than the US Federal Government), in which any "official" copyright has either expired, or where the governmental entity concerned releases its work under a license compatible with Commons.
