Confusion about Amit Kalani Book

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.

ISBN 0789728222
This one attempts to teach ASP.NET 1.1. This is the one that
is usually recommended.

ISBN 0789729016
This one is merely a review of the topics i.e. it does not
attempt to teach - use it to discover your weak areas and
then use other materials (MSDN, other books for, usually
some references are given inside the book) to fortify them.
This is NOT the book that is generally recommended.

There is no point in getting both. Most people will benefit
most from the first one - only few will benefit from the
second one.

 

Thank you UAError for the clarification.
