Copyright protects original works of authorship and gives the author ownership over published materials like books, music, and images. However, ownership can be complicated when works are merged or created by multiple people. The TEACH Act provides additional fair use rights for educators to display copyrighted works in classroom settings. Fair use is assessed using four factors to determine if unlicensed use is permissible. Proper attribution and permissions are required when using or borrowing others' copyrighted work.
