This volume considers the theme of the protection of the user in the field of information technology, and more specifically in relation to software licences, electronic information services and Internet access services. Litigation in IT usually stems from the users' feeling that their expectations have been frustrated at performance. When dealing with such cases, the courts seem to increasingly take the objective of user protection into account. How is this protection implemented? Is this trend generally desirable? Is this judicial protection excessive? What are the constraints met by IT providers that should be taken into account in litigation? How can the user's position be improved?
