This book gives a good survey of the equipment available from various manufacturers, both bows and accessories. It was published in 2005, so it may be a bit out of date, but the kind of equipment available probably hasn't changed much since then. This provides the information as it might come from the producer's catalog, and does not include the kind of comparative information one would expect of a review of the equipment (a la Consumer Reports), nor does it provide any technical information, such as any test results. It has a few general archery articles in the front of the book, and various tips scattered throughout. It is worth the purchase price, but I wouldn't call it "Ultimate".
