Never seen it on line to read. You can purchase it on line though. It is well worth the money and is good to have around to refer back to at times.
I had to order it through a book store and gave them a false phone number so they wouldn't accidentally reach one of my dub family and start questions I didn't want to answer. Just showed back up to the store after a week and picked the book up. I actually read it in front of my family at times with a slip cover from another book over it. Worked great!
It is sold through Commentary Press on line.
