This book is a gorgeous coffee-table volume. It is divided into sections by time periods beginning in the 1840s and continues to the present. Each chapter is introduced with an in-depth discussion of what was happening at that time, then moves to captioned photos. The book is large, 10"x12", and is presented on heavy, high quality paper; a pleasure to hold and look at! My only criticism is that readability was sacrificed for design. The type is very small and, therefore, difficult to read, and the caption reference number below each photo is mircoscopic. Also, even though I'm sure the photos were reproduced perfectly, some are hard to make out (what do I expect for 100+ year old photos!) I recommend this book whether you are interested in this subject, interested in photography or just love beautiful books.
