Creative Commons Licences

Creative Commons is a licencing system that allows you to share, remix and reuse material legally.

Creative Commons describes itself as “a non-profit organization that develops, supports, and stewards legal and technical infrastructure that maximizes digital creativity, sharing, and innovation.

The infrastructure we provide consists of a set of copyright licenses and tools that create a balance inside the traditional “all rights reserved” setting that copyright law creates”
