This document discusses copyright law and what educators can legally use in their classrooms without obtaining permission. It notes that copyright law is complex with over 300 pages of regulations. Under fair use, educators can display and perform copyrighted works for educational purposes. The document outlines exceptions for educators under the TEACH Act and explains resources like public domain works, Creative Commons licensing, and collective rights organizations that allow more flexible use of copyrighted material. It provides guidelines for determining fair use and notes that widespread commercial use or use that replaces the original work would not be considered fair use.
