Public Domain Mark

The Public Domain Mark (PDM) is a label used to indicate that a work is no longer under copyright protection and is freely available for use by anyone. It helps identify works that are in the public domain, meaning no one owns the rights anymore, allowing for copying, sharing, and reusing without permission or restrictions. This mark makes it easier for people to discover and access freely available content, supporting open sharing and creative reuse of historical, cultural, or otherwise protected works that have entered the public domain.
