Copyright is protection provided to authors of fixed literary, dramatic, artistic, and musical works as well as some other intellectual works, published and unpublished. The owner of a copyright has the exclusive rights to use the copyrighted work for reproduction, distribution, creating derivative works and public display of the work. Copyright protects the form of expression but not the subject matter, protecting for instance, the way an author described a cat but not preventing anyone else from writing their own description of a cat – as long as it is not copied from an original work. The Library of Congress registers copyrights. Registered copyrights of works created since 1978 last the life of the author plus 70 years. For works "made for hire", the duration of copyright will be 95 years from publication or 120 years from creation, whichever is shorter. Some treaties extend copyright protection in member countries.
