2. Fair Use: What is fair use?
The U.S. Copyright Act is designed to encourage both the creation and sharing of knowledge. It does so, in part, by creating a balance between the rights of creators and the rights of users of copyrighted works. The rights of users are defined by a number of exceptions to the exclusive rights of the creator. Fair use is the most commonly used of these exceptions.
Fair use is described in Section 107 of the U.S. Copyright Act. Unlike other copyright exceptions, fair use is rather flexible. It is designed to be adaptive of new uses and technologies so that Congress doesn’t have to create new exceptions before a new technology can be utilized.
