Google Books just keeps getting better and better. Now we see embedded links, improved search within each book itself, a thumbnail view, contents in a drop down menu and even plain text books!
Perhaps most important of all though, is the improvements made with the book overview page. This can make or break whether or not one is going to select a book from what is available.
Just the layout itself will translate into easy access to ratings, reviews, and other critical data that one would like to have access to when browsing books off of Google Books. Despite Google Books still have having some ways to go before getting to a level where Amazon needs to be worried.
