I take off 1 star for the Kindle version. It has a ToC but not linked in "Go to". You have to go to the beginning and click forward 8 times to get to ToC and also some subject matter under ToC are not linked at all. So you have to go to the closest subject(with a working link) to what you intend to read and click forward to get there. I requested a refund for this and will just buy the hard copy.
