The use of the internet is transforming our knowledge about health and illness and this creates opportunities as well as dilemmas for users, health professionals, the health services and the health care industry. In this book, Michael Hardey explores the world of health on the net with a sociologist's eye for meaningful contradictions. The result is a fascinating account of our current attitudes to health as he maps a largely neglected sociological territory. From 'global resources and local dilemmas' to 'mystification and authenticity', this is an important contribution to the growing literature about the internet that will appeal to a broad readership.
