What is Copyright?
United States federal Copyright law grants the creator of an original work a number of exclusive rights. Copyright protection assumes three elements: the work is original, minimally creative, and fixed in a tangible format. Examples of works that fall under copyright protection include books, articles, sound recordings, images, art works, motion pictures, sound recordings, choreography, to name a few. The six exclusive rights are (in abbreviated form):
— The right to reproduce the work
— The right to prepare derivative works
— The right to distribute copies of the work to the public
— The right to perform the work publicly
— The right to display the work publicly
— The right to perform the work by means of a digital audio transmission.
These exclusive rights are not absolute, and they may be unbundled and transferred to someone else: for example, an author may sign over book printing and distribution rights to a publisher. The rights are also limited in duration and are subject to a number of other exceptions. These exceptions, or limitations, permit use of a copyrighted work without the copyright holder's permission under certain conditions (see sections 107 - 122 of Chapter 1). A brief discussion of one of these limitations follows.
What is Fair Use?
One of the limitations on the exclusive rights of the copyright holder is found in Chapter 1, section 107 of United States Copyright Law. Fair use allows scholars, students, teachers, and others to use works that are still in copyright protection for the purpose of education and criticism. Fair use is intended to be a defense against copyright infringement by allowing people a degree of freedom in using the works of others to create new works. The four factors of Section 107 are a set of guidelines for evaluating whether use of a copyrighted work is 'fair use,' and are not hard and fast rules. For example, in a copyright infringement case, a court would weigh all four factors:
— The purpose and character of the use
— The nature of the copyrighted work
— The amount used
— The effect on the market for the work
One of the uses specifically mentioned in the purpose clause is education: "the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes." This does not mean that any use is fair as long as it is for educational purposes, as the three remaining factors must also be weighed, but education is specifically mentioned as a favored purpose.
To guide practitioners in their work, some associations and organizations have issued fair use guidelines. Guidelines describe uses that are generally agreed to be fair. It is important to remember, however, that guidelines are not law, they are usually conservative interpretations for a specific context, and as such, may represent minimum guidelines for use. For example, if a guideline recommends using no more than 10% of a copyrighted work, it is not necessarily true that using 15% or 20% cannot be fair.
How can I protect my works?
When U.S. Copyright Law was revised in 1976, registration and notification requirements were eliminated. Your work is automatically copyrighted as soon as you fix it in some medium (paper, computer disk, videotape, etc.). You are not required to place a copyright statement on your work or register it with the copyright office, but it is a good idea to consider doing one or both. A copyright notice advises potential users that the work is protected and identifies you as the copyright holder. Registration is required before you can bring a lawsuit against someone who has infringed on your copyrights.
