Copyright

Copyright affords an author a number of exclusive rights: (1) the exclusive right to reproduce, or copy, the work; (2) the exclusive right to prepare new works that derive from the copyrighted work; (3) the exclusive right to distribute the work to the public by sale or other arrangement; (4) the exclusive right to perform the work publicly; and (5) the exclusive right to display the work publicly. The first two rights, involving reproduction and derivation, are infringed whether violated in public or in private, or whether violated for profit or not. The last three rights are infringed only when violated publicly, that is, before a "substantial number of persons" outside of family and friends (17 U.S.C.A. § 101).

All of the exclusive rights afforded by copyright may have significant economic value. For example, derivative works, which may include translations, dramatizations, films, recordings, and abridgments, can offer substantial rewards to the author. An author may sell, license, or transfer one or all of the exclusive rights.
