5-star book, 1-star service.
As for a previous reviewer, Amazon sent only volume 1 of an expensive two volume set. Their service is usually excellent, so I am surprised that after screwing this up once for another customer, they still didn't get it right. I am sending it back and ordering it directly from the publisher.
My one-star review is intended as a rebuke to Amazon, not to the authors. Make no mistake--this text is excellent and a critical reference in its field. It definitely deserves five stars. But neither the authors or Amazon's loyal customers are well served in this instance. Definitely buy it--just not from Amazon. They've had the opportunity to fix their problem, and didn't take it.
