Using Public Domain Works

What is the public domain?

The public domain is a collection of works that are not subject to copyright law. When a work is in the public domain, you can freely copy, distribute, display and perform the work, as well as make derivative and commercial works.

There are three classes of public domain works:

  • Works that automatically enter the public domain upon creation, because they are not copyrightable:
    • Titles, names, short phrases and slogans, familiar symbols and numbers.
    •  Ideas, methods, and facts
    • Works consisting  of information that is common property and contains no original authorship. 
    • Government works and documents
    • Works that have not been fixed in a tangible form of expression 
  • Works donated to the public domain by their creators.
  • Works that have entered the public domain because the copyright on them has expired.
