I am in a class in college where this book was a necessity. I searched by book code, and the edition that came up in paperback looked right. I saw that the Kindle edition was much cheaper, and went for it. I was terribly disappointed to find that this Kindle edition is the WRONG or MISMATCHED edition, and that the paperback is completely different. I ended up having to buy the hard copy instead. Terrible quality, and it doesn't even allow you to jump to pages you want to read, doesn't register the text as text, and appears very faded as opposed to the crispness of all my other Kindle books. Do not get this.
