Copyright is a legal right, existing in many countries, which grants the creator of an original work exclusive rights to determine whether, and under what conditions, the original work may be used by others. Usually copyright is only valid during a limited time. The exclusive rights are not absolute, because there might exist some limitations and exceptions, including fair use. Copyright is applicable to certain forms of creative work and frequently includes reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution. Copyright might have different legal framing in different countries.
