If you really want to know what you're looking at when you visit Rome, this book is a must for your suitcase! It is brisk, erudite, academic but highly accessible and fascinating. The layout is useful, too, with introductions relating to the building materials and general history. I was given it for Christmas so had plenty of time to read it before we went to Rome in March for a wonderful six days. It hugely contributed to my enjoyment of this fantastic city, where there is little interpretation of the archaeology on the ground, as it were, with a complete lack of signs, identification and interpretation. You still need a tourist guide book to get you to the sites, though, as there is no overall map of the city in the book, guiding you to where stuff is on the ground now and how to find it. Thanks to this book, we visited sites off the beaten track and got far more out of our visit than we might have done.
