A full disclaimer. There was much in this book that the reviewer understood vaguely, if at all. Then why not give the book to a more learned scientist? Because a clinical dermatologist should be able to take something useful away from a book about sun protection.
Needless to say, this book is not primarily a how-to guide on hats and sunblock, but a comprehensive reference text written by and for photobiologists. Austerely subdivided into dense sections, subsections, and sub-subsections, it focuses on the tissue effects of solar irradiation. Since the same scientific problems are approached from many angles by many contributors, there is inevitable redundancy. And some of the science appears to be at the edge of knowledge, more about process than content.
