The Fair Use Doctrine provides for limited use of copyrighted materials for educational and research purposes without permission from the owners. It is not a blanket exemption. Instead, each proposed use must be analyzed under a four-part test.
"Limitations on exclusive rights: Fair use" (Section 107) offers a set of factors to consider when using copyrighted work for teaching or research. Specifically, the factors include:
The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes
The nature of the copyrighted work
The amount and substantiality of the portion used in relation to the copyrighted work as a whole
The effect of the use upon the potential market for or value of the copyrighted work
