It's not often you find a coffee-table style book devoted to the martial arts but this really is a hefty, large format tome filled with lots of high quality colour photographs.
This could equally well have been titled, "The Dorling Kindersley Colour Encyclopedia of Martial Arts" since it IS really comprehensive. It covers everything from Zulu stick fighting to pro boxing to sumo, with each sport covered in almost an equal level of detail. However, its main selling point is the huge number of large, action photos in each section which capture the excitement (and danger) of fighting sports.
I don't usually like buying books with cover prices of £25 but due to the size and quality of this hardback I have to admit it does offer value for money. However, it's probably more suited to the shelves of a public library than the home of a practising martial artist or boxer or wrestler.
