Barcode Scanner application is a new searching tool available for 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.
This is the first release of this program, so there may be some hiccups. Most of the books supported by this tool were printed in the mid-1990s or later, because it took some time for ISBN barcoding standards to stabilize. And of course, not every book is on Google Book Search. Yet even with these limitations, it’s a lot of fun to search through a paper book using your mobile device, and I think the tool opens up new ways to experience printed works.Google Book Search Blog
