Creative Commons licenses provide free and easy-to-use copyright licenses that enable sharing and reuse of creative works. They allow creators to select which rights they reserve, such as allowing only non-commercial reuse or requiring derivative works to use the same license. The licenses cut out middlemen and make it simpler for creators to exercise their rights while enabling widespread sharing and reuse. They consist of human-readable license deeds and machine-readable metadata to help others find works with Creative Commons licenses.
