Copyright law (from Title 17 of the United States Code)
Copyright Law protects "original works of authorship fixed in a tangible medium of expression" for a limited period. Copyright protection includes, for instance, the legal right to publish and sell literary, artistic, or musical work, and copyright protects authors, publishers and producers, and the public. Copyright applies both to traditional media (books, records, etc.) and to digital media (electronic journals, web sites, etc.).
Ownership of a copyrighted work includes the right to control the use of that work. Use of such work by others during the term of the copyright requires either permission from the author or reliance on the doctrine of fair use. Failure to do one or the other will expose the user to a claim of copyright infringement for which the law provides remedies including payment of money damages to the copyright owner.
