What is Public Domain?

When a work is in the public domain, it can be freely used by anyone for any purpose without restriction under copyright law. Public domain is the purest form of open/free, since no one owns or controls the material in any way. 

When does something fall into the public domain?

  1. The term of copyright for the work has expired. Most content in Europe comes in the public domain on the first of January of the 71st year after the death of the creator. 
  2. It never had copyright protection. 
  3. The work was explicitly donated to the public domain.
