[This book] is a bit of a treasure trove. It is difficult to imagine a better-researched volume ... .It is jam packed, even impacted with good bits. It is fantastic to have access to so much information, which is so clearly authoritative but sometimes a bit tricky to navigate. If you are interested in this area you will cherish this book as a rock. (Disease in Childhood, March 2007)
