If you are thinking about ordering this book, think about why you want it. It is a small paperback book with only black and white photos, not a coffee table book. It is intended to be carried around the city with you while you look at the buildings. With that said, it contains photos and descriptions of 167 buildings and additional information such as a glossary and a list of buildings that have been destroyed since they appeared in previous editions.
