I chose this book on the basis of reading the previous three reviews. The book is split into regions of London. Each region has a detailed map. This map shows the location of each building listed and a code. The code given locates the details of the building within the text of the book. The details include, a picture, cross referencing to other buildings, the architect/s involved in its construction, a brief discription (not really fair to call them brief),nearest tube location, and sometimes, an opinion as to the architectural value of the building (they can be amusing; but generally true). I apologise for making my review a little wooden, but the previous reviewers have all made comments which I can only agree with. This is the best book of this kind I have ever read, about any city, anywhere in the world. Thanks from me must go to whoever was involved in putting it together.
