Got a web reference to an article “Applied MVC Patterns. A pattern language” by Sergey Alpaev.
Model-View-Controller is one of the most complex and pribably the most misinterpreted patterns among GoF’s.
The article is a perfect classification, I recommend it as a must read for everyone who is confused about what is Controller for, and to those who already know it.
Wikipedia article also has some very basic analysis of the pattern.
