content: The book delivered by Amazon.com looks like a photocopied book, not a printed one. Paper quality is the worst. It's totally incompatible with the US$ 140 price.It should be out-of-print or something and then Prentice-Hall found it cheaper to photocopy and bind it, rather then issuing a new edition. Amazon.com should let customers know this in advance.The book content is great as the other reviewers have said, but I'm about to see a book with worse print quality than the one Amazon sent me.I wish I have bought a used book, printed 15 years ago, for US$ 40.
