This document discusses copyright and fair use guidelines for educational use of copyrighted materials. It outlines the four factors of the fair use test: the purpose and character of the use, the nature of the work, the amount used, and the effect on the potential market. It provides specific guidelines for how much of different types of copyrighted works (words, music, illustrations) students can use under fair use. It advises educators to be cautious and avoid the "gray zone" by either creating their own materials, using Creative Commons works, or subscribing to media services when possible.
