I bought this as a second hand copy, described as 'Used - Very Good'. The delivery was exceptionally fast as it arrived days before the predicted delivery dates. The book was also in much better condition than I had expected - it is as good as new. I am very pleased with the service from Amazon, the Amazon seller and the delivery service. This is especially true considering the remarkably competitive pricing - it was by far the cheapest place to source this particular book which is a major point in its favor. Textbooks can become pricey for students but this was very good value for money. I can not comment especially on the content as I bought the book primarily because it was on a university reading list, but this in itself suggests that it has some academic credit.
