Internet content is protected by copyright in the same way as printed works, however authors implicitly grant a limited license for others to view, download, and share their work. To determine if fair use applies when using copyrighted material, one should consider the purpose of the use, nature of the work, amount of the work used, and the effect on the original work's market. The TEACH Act provides additional rights for educators to display and perform others' works in class beyond fair use. If fair use does not apply, permission is required and can be obtained from organizations like Copyright Clearance Center for books and images.
