When deciding to use a work protected by copyright, the general rule is to seek permission from the copyright owner. Provisions in copyright law make certain uses of copyrighted works permissible without first obtaining permission of the copyright owner. The provision on fair use promotes freedom of expression by permitting the unlicensed use of copyright-protected works in certain circumstances.
