Copyleft

Copyleft – a form of licensing that makes a creative work freely available to be modified, and requiring all modified and extended versions of the creative work to be free as well. Open Access does not require works to be copyleft, nor does it necessarily exclude copyleft works from being open access. The recommended licence (CC-BY) for academic publishing is not copyleft.
