I am the joint author of the main practitioner's textbook "Electronic Commerce: Law and Practice" published by Sweet and Maxwell. The book is now out of date and there will not be a new edition. The right equvalent product today would be a website/wiki with RSS feeds for an e-book. But the legal publishers do not appear to be ready for this concept.

On the topic of Electronic Commerce I can advise on all legal aspects of developing new technology businesses. Check out my CV and you will see areas where I am likely to be able to assist you. If you are not sure just e-mail me. Ali Kelman
