Copyright is a form of legal protection for authors of original works, including literary, dramatic, musical, artistic, and other intellectual products. Publication is not essential for copyright protection, nor is the well known symbol of the "encircled c" (©). Copyright provides these creators with a set of limited exclusive rights. The law balances the private interests of copyright owners with the public interest and is intended, in the words of the Constitution, "to promote the progress of science and useful arts, by securing for a limited time to authors and inventors the exclusive right to their respective writings and discoveries."

The public domain is generally defined as consisting of works that are either ineligible for copyright protection or works whose term of copyright has expired. No permission is needed to copy or use these works. Public domain works and information represent some of the most critical information that faculty members and students rely upon and they can be quoted extensively. They can also be copied and distributed to classes or digitized and placed on course web pages without permission or paying royalties.

Creative Commons is a nonprofit organization that enables the sharing and use of creativity and knowledge through free legal tools.
Our free, easy-to-use copyright licenses provide a simple, standardized way to give the public permission to share and use your creative work — on conditions of your choice. CC licenses let you easily change your copyright terms from the default of “all rights reserved” to “some rights reserved.”
Creative Commons licenses are not an alternative to copyright. They work alongside copyright and enable you to modify your copyright terms to best suit your needs.

One such exemption is fair use, which allows users of copyrighted works to exercise certain rights without seeking permission or paying royalties.
The complexity of the Fair Use Doctrine and its importance in academia make it imperative that every member of the campus instructional community understands how to make judgments concerning fair use. The information and tools that follow are designed to assist your decision-making. When combined with a thoughtful consideration of the legitimate interests of copyright owners, they will help assure good faith applications of fair use at the university.
The determination of whether the use of a copyrighted work is within fair use depends upon making a reasoned and balanced application of the four fair use factors set forth in Section 107 of the U.S. Copyright Act. These factors are as follows:
