This is the Global Edition. I know it says so in the title, but for some reason - it was not obvious to me when I ordered it. My professor let me use it, because it is really REALLY similar to the 12th edition. If he says turn to page 100, add 26 pages - at page 126 will be there right area where he is at on page 100. Hope that makes sense. This is a good book. I am not remotely intelligent when it comes to physics, but this book does a good job of explaining it in everyday language.
