Creative Commons
Creative Commons is an imaginative and workable response to the stifling effect of copyight on creativity. It effectively protects the authors rights, but allows and encourages the creative use of information. The current issue of Information Today provides free access to a detailed article explaining the relevance of the Creative Commons idea. UK readers should note that the legal explanations relate to US law, and that copyright law in the UK is different.
