Good, but light on practical information.
This book does a good job covering all the main sites of Moscow. The illustrations are very detailed and intense. I think it would best fit someone who is only in Moscow for a day or two, and just wants to hit a few of the touristy attractions. I bought this book, but also purchased the Fodor's guide to Moscow and St. Petersburg. Fodor's has much much more practical information - such as best days and times to see certain things, places to avoid, where to buy the best souvenirs, where to stay away from .. etc. It is also much more subjective and they offer their opinions on certain sites. This guide does not offer this subjectivity, and only offers very general and limited practical information.

great
good guide book if you are primarily looking for photos and maps. Not much specific info.

New Edition is Wonderful.
I really like the new edition of the book. It is quite accurate, and easy to use while exploring Moscow. As with all these DK guides, the photographs and accompanying text offer a unique companion to your travels. My only complaint is the sections on sites outside and around Moscow are weak. More people need to explore outside the city.

One of an excellent series of travel books
I have used this series for other cities and have found them always excellent, the best at what they do.
