Windows: GooReader is a desktop application for Google Books that allows you to search, read and even download the books and magazines you find.
The web-based interface for Google Books is functional, if a bit spartan, but GooReader offers a polished interface. You'll get a better look at the covers, a book-like page turning experience instead of vertical scrolling and easy-to-use search.
In addition to enhancing the display and search functions of Google Books the premium version ($US20) also supports saving and PDF creation — only documents available for download, GooReader won't download protected documents. Check out the video above to see GooReader in action. GooReader is Windows only and requires .Net 3.5 or above.
