How to Download Page/s from Google Books?

You can download page/s from Google-book by two ways. 

1.  Google Books Downloader for Windows and Mac OS X
   
   
   As announced by Google, the aim of this project is to provide users with their own bookshelf on hand, no matter where they are. Purchased or downloaded books can be read using a desktop browser, as well as through mobile devices based on the Android operating system or iOS. Additionally, the books can be read on any e-reader with Adobe Digital Editions software.
   As opposed to the Picasa service which provides an access to photos, the Google Books service does not allow users to download free electronic editions without digital copy protection and use them on other devices. Google Books Downloader is a little software that allows you to save these books in PDF, JPEG or PNG format (note: it supports only the books marked as "full view").
