This article provides an introduction to the use of the Creative Commons licence system, and sets it in a historical, economic and political context. It is written from the perspective of involvement in open educational projects in an arts university that has used the licences. A description of the fundamental features of the licences and their uses is given, together with an outline of how the Creative Commons organisation works and its strategic aims. An assessment of the usefulness of these licences is provided, together with a description of the challenges faced in dealing with low levels of legal awareness amongst academics. Practical advice and sources of further information and guidance are offered to help readers implement the licences locally.
