A very good book.

If you use Google a lot

and haven't mastered the capabilities involved

(such as allowed by special syntaxes),

likely you'll learn far more than enough from this book

to justify the cost.

If you are a programmer and

you are primarily interested in this book

for what it can teach you about the

Google Web API,

this is likely a good book for you too.

However, I suggest looking around for another review

as I didn't use the API or write any programs based on this book.

And/or you may wish to take a look at the

table of contents and

browse the book on Safari.
