This document summarizes the purpose of copyright and fair use, and discusses the Code of Best Practices in Fair Use for Academic and Research Libraries. It outlines that copyright aims to promote culture by rewarding creators, while fair use allows unauthorized use of copyrighted works under certain circumstances. The Code was created by librarians to provide guidance on applying fair use in eight common library situations, such as using materials for teaching, exhibits, and digital collections, while noting applicable limitations and enhancements. The goal is to help librarians apply fair use principles in their work.
