The rights of a copyright holder are not unlimited, and one major limitation of great value for instructors is the doctrine of fair use. Fair use is an open-ended doctrine which allows the public limited use of a copyrighted work without the holder’s permission.
For fair use documentation you are required to use the Fair Use Checklist. As you use the checklist and apply it to your situations, you are likely to check more than one box in each column and even check boxes across columns. Some checked boxes will favor fair use and others may oppose fair use. A key issue is whether you are acting reasonably in checking any given box, with the ultimate question being whether the cumulative weight of the factors favors or turns you away from fair use. This is not an exercise in simply checking and counting boxes. Instead, you need to consider the relative persuasive strength of the circumstances and if the overall conditions lean most convincingly for or against fair use. Because you are most familiar with your project, you are probably best positioned to evaluate the facts and make the decision.
The text of the Fair Use doctrine from U.S. Code Title 17 is given below:
Ҥ 107. Limitations on exclusive rights: Fair use
Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work…for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include—
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.”
