The book is long, but readers will find the effort well worthwhile ... It is difficult to do justice in a review to a book of this magnitude. The book provides a valuable set of data and convincing arguments to support the typology proposed ... A value of the book is that the proposed typology provides a solid foundation for future empirical investigation. The book is the second in a series on typology. I hope that subsequent volumes in the series will be of such a
high quality.
