This book, if I'm not mistaken, is currently in its 11th edition, and my prof. still uses the second edition. I never expected to get such a good book. The price was phenomenal, especially for a college kid going to private school. I expected something that had pages with bent corners (drives my engineer mind CRAZY) and highlighter all over the pages. But no, I picked it up from receiving in a bubble wrap-lined manilla envelope, and it was still in the original vacuum-sealed plastic wrap! I opened it up, and it still had that new book smell, the binding crackled when I opened it, and not a mark was on it! The binding still hasn't worn in 8 weeks later. Great book, great price, exactly as it said. Shipped the next day. Arrived within 3-5 days.
