If you are student of Ralph Kimball, I am sure you had mixed emotions when he retired. The good news is Margy Ross & Bob Becker are still going strong. They are doing business at DecisionWorks Consulting http://decisionworks.com/. There is more good news. They updated the Kimball Group Reader and the Kindle version is currently on sale. The title is The Kimball Group Reader, Remastered Collection.
