The Copyright Act protects the rights of creators of literary, dramatic, musical, artistic works and films. Copyright provides creators with exclusive rights such as reproduction, communication to the public, and adaptation. These rights last for 60 years from the death of the creator or publication for most works. Infringement occurs through unauthorized use, copying, distribution, or display of a copyrighted work. Common infringements include selling unauthorized copies or public performances. Certain uses such as research, teaching, and criticism are exempt from infringement.
