How much of a work can I put on reserve?
If you plan to assign book chapters in your class but do not require students to purchase the entire book, you should follow the guidelines for Fair Use regarding the amount of the total work that you photocopy or post on a course site. If you require that students read several chapters or a substantial proportion from any given work, it is better to place a copy or copies of the book on reserve or require that your students obtain their own copies. While there are no specific restrictions on the amount, your library may enforce its own guidelines.
