[EX Q]: The best thing I found in this book is the picture on the cover. Well, actually the uncropped version in chapter 5. Beyond that, I found everything else to be non-practical from a design perspective. A photo of a filthy dust collector area when discussing the advantages of central collection or electrical wiring that would never pass inspection is typical. I'd rather see plan views of real shops that work with reasons for the decisions made.
[EX A]: Negative

[EX Q]: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.
[EX A]: Positive

[EX Q]: Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
[EX A]:
Positive
