I am a practising publisher and I approach the task this afternoon very much with that kind of bias. I am not an academic and I am not a real lawyer. I am a practising publisher with an interest in copyright. One of the most fascinating things that has happened over the last five to ten years is the way that interest in copyright, from being a rather arcane minor hobby of one or two people like myself in publishing, has suddenly become a central battlefield in the book world. What I want to do is to sketch in very broad terms some of the major battle sites.
