University of Maryland, University College, has developed a series of resources to help educators determine their ability to claim fair use in an academic setting. This document outlines the basics of copyright and fair use and included a sample letter that can be used by academics or students to request permission to use copyrighted materials. To help educators make judgments on what is (or is not) Fair Use, this document includes various guidelines such as the amount of time for which a claim of fair use holds, or the percentage amount of a complete text that can be reproduced legally.
