Creative Commons
Creative Commons is an international non-profit organisation that provides free licences and tools that copyright owners can use to allow others to share, reuse and remis their material, legally. Releasing material under a CC licence makes it clear to users what they can or cannot do with the material. There are six standardised CC licences and each allow material to be used in a different way.
