How to Obtain Permission to Use a Copyrighted Work
Permission is not required for every use of a copyrighted work, and not all unauthorized uses are infringing. But copyright law gives owners of copyrighted works a bundle of exclusive rights, including :
the right to reproduce their works or authorize others to reproduce them,
subject to certain limitations defined in sections 107 through 122 of the copyright law.
To determine if a particular use requires permission from a copyright owner, you need to evaluate whether one of these limitations applies to the use. The Copyright Office cannot grant permission to use copyrighted works.
