Copyright gives creators exclusive rights over their work, including reproduction, distribution, derivatives, public performance, and display. Fair use allows limited use without permission for purposes of criticism, commentary, news reporting, teaching, scholarship or research. Determining fair use considers the purpose and character of the use, nature of the work, amount used, and economic impact. Educational use alone does not guarantee fair use; all factors must be considered. The Digital Millennium Copyright Act updated copyright for the digital age but is still being adapted for new technologies.
