For students, this could be an easy way to locate that critical passage that the professor was talking about in lecture. Or if you're browsing through the shelves of a bookstore, you could use this application to easily determine whether a book contains the information you're looking for.

The Last Lecture was one of the first books we tested on the Barcode Scanner application, a new searching tool available for download on Android-powered phones. Here's how it works: when you open up the application, the screen will show what the phone's built-in camera is seeing. When you line up the camera in front of a book barcode, it will automatically zoom, focus and scan the ISBN - without you even needing to click the shutter. As you can see below, you'll then have the option search the full text of the book on Google Book Search right away.
