This book isn't intended for the astronomical data-miner or the budding astrophysicist so if you buy it expecting to find a detailed analysis of data management techniques or the latest theories on double star formation you will be greatly disappointed. But if you are an amateur astronomer interested in observing double stars this book will fill your heart with joy. If you are tired of seeing the same old lists of double stars with the same, decades old, descriptions then you will love this book because none of these 1800+ double stars have ever been catalogued before The first few pages contain an introduction the catalogue - the why and the how behind its creation. The heart of the book is a detailed list of these new targets organised by constellation and then by right ascension within the constellation. Detailed information on coordinates, magnitudes, separation, position angle and colour is given for every pair. This book represents a major step forward in popularising double star astronomy.
