If you want to know more about using Chrome this book is a good resource. It shows you how things look on your screen when you click on an icon or a tab, walks you through menus, etc. The Chrome OS updates itself so there may be some things in this book that are no longer current, or you may have a different version, such as the version I have with Logitech's Revue Companion Box with Google's Smart TV. But I find it very helpful because it provides definitions and explanations that I can't always find with Google Search. I'm still reading the book, but I find myself saying, "Oh...THAT'S what it's for..."
