Rated 5 out of 5 stars

Five starts for historical work, 1 star for current version. I am sure the bugs will be worked out. If you really have a problem with the current edition, contribute. I am sure the authors would love to get your feedback and bug reports. I am sure they could use some help with testing. And I know they would appreciate $10 to help them keep going.
