"Fair use" is use of copyrighted material that does not require permission or payment of royalties. In deciding whether or not a particular use of particular material is fair use, the law states that the following four factors should be considered:
"(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." (U.S. Code, Title 17, Section 107)
