Copyright protects original creative works and grants exclusive rights to authors and creators. It began in the 16th century with Johannes Gutenberg's printing press. The document then provides examples of fair use and restrictions on using copyrighted works for educational purposes, noting that limited use of fact-based or less than 10% of creative works is usually allowed, but to always check guidelines. Teachers should ensure any use of copyrighted material in the classroom is for educational purposes and falls under fair use provisions.
