Google Print
http://print.google.com/
To use Google Print, just do searches on Google as you normally would. Whenever a book contains content that matches your search terms, we’ll show links to that book in your search results. Click on the book title and you’ll go to a “content page,” where you can see the page containing your search terms and other information about the book. You can also search for other topics within the book. Click on the “Buy this Book” link and you’ll go straight to a bookstore selling the book online.
