Copyright law protects any original creation, and grants the holder of the copyright exclusive control over when, how, and by whom their work may be copied, distributed, or exhibited. This includes literary works, paintings, photographs, drawings, films, music (and its lyrics), choreography, sculptures and many other creative works.
Copyright law generally does not protect the underlying idea of a creative work. And it does not protect facts. For example, copyright doesn’t prevent you from expressing in your own words ideas and facts found in a book or journal you read.
