Copyrights, copyright texts, defines who has rights to (e.g.) copy, distribute, perform or display work in public, sell or assign rights to others, transmit or display by radio or video, reuse and modify works based on it. See copyrightswiki - wikipedia article for more.

One example:

Creative Commons Attribution License

To ensure the legal reusability of content, Connexions requires authors to license materials they publish under the Creative Commons Attribution License [1] (presently, version 2.0). Under this license, the author retains the right to be credited (attributed) wherever the content is reused. The author grants others the right to copy, distribute, and display the work, and to derive works based on it, as long as the author is credited. (From wikipedia article on Connexions.)
