A copyright protects the creator of an original work from unauthorized copying. To use a copyrighted work, permission must be obtained from the copyright holder. For works created after 1978, copyright lasts until 70 years after the creator's death, while older works have copyrights from 28-67 years. Creating an original work automatically grants a basic copyright, but registration provides additional legal protections. More information is available from the U.S. Copyright Office.
