Copyright at the University of Northern Iowa: Public Domain & Orphan Works

What is Public Domain?

A public domain work is a creative work that is not protected by copyright and which may be freely used by everyone.

When is a Work in the Public Domain?

Works fall into the public domain for three main reasons:

1. the term of copyright for the work has expired;

2. the author failed to satisfy statutory formalities to perfect the copyright or

3. the work is a work of the U.S. Government.

As a general rule, most works enter the public domain because of old age. This includes any work published in the United States before 1923. Another large block of works are in the public domain because they were published before 1964 and copyright was not renewed (renewal was a requirement for works published before 1978.) A smaller group of works fell into the public domain because they were published without copyright notice (copyright notice was necessary for works published in the United States before March 1, 1989).

Use the Copyright Slider Tool to determine if a work is still protected by copyright.

 

Orphan Works

The term "orphan work" is used to describe a situation where it is difficult or impossible to contact the copyright holder of a copyrighted work. There are two ways an item can be orphaned:

  1. The identity of the rights owner cannot be determined;
  2. The identity of the likely rights owner is known, but he or she cannot be located.

Some have proposed that the failure of a rights owner to respond to a request to use a work also makes that work an orphan, but this definition has not been adopted in the proposed legislation.
