What is fair use?
Fair use is a doctrine under copyright law that permits certain users of a work without the copyright holder's permission. Fair use is an exemption to the exclusive rights of copyright holders. Fair use may be used for a copyrighted work for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use, scholarship, or research).
