Copyright Term and the Public Domain in the United States
Digital Tools (from the American Library Association Office for Information Technology Policy)
The public domain knowledge, information and works are no longer protected by copyright law. For example U.S. Government works are in the public domain, but not the works created by state governments. Facts also don’t fall under copyright law. They are in the public domain. (Carrie Russell, 2004)
