Fair use allows for the reproduction of copyrighted material under certain conditions. The exact conditions under which fair use applies is not spelled out; rather fair use can be claimed in defense of a copyright infringement claim. The purpose and character of the use, the nature of the copyrighted work, the amount used, and the effect of the use on the market are the four considerations used by courts to determine fair use. > [!Tip]- Additional Resources > - [What is Fair Use](https://copyrightalliance.org/faqs/what-is-fair-use/) Copyright Alliance > - [U.S. Copyright Office Fair Use Index](https://www.copyright.gov/fair-use/index.html)
