Fair Use refers to the copying of copyrighted material, without the permission of the copyright owner, typically done for the purposes of criticism, news reporting, teaching, scholarship or research, and parody. Users claiming fair use of copyrighted material must be prepared to defend their use if challenged by the copyright owner. There are no precise rules for determining whether a use is fair. Copyright law provides guidance only by way of the four factors for which a use is judged.
Fair use does not preempt or supersede licenses, terms of agreement, and contractual obligations. ( IE Netflix, Amazon Prime, ETC)
Note: Section 504 (c)(2) of the Copyright Act of 1976 offers legal protection to educators and librarians who have used copyrighted material based upon a good-faith analysis of the fair use factors.
