I was looking on internet to buy Amit Kalani's book for Web applications exam and I came across two different books with the almost the same title. Please look at the following links to see the two books (The link might break to fit in the window, please copy and paste it in browser). Which book should I buy and what is the difference?? Thanks in Advance.
