This book is quite nice for the spoiled programmer who has been using a modern OO language such as C++ or python, and demonstrates methods to implement OO concepts as classes, overloading and polymorphism in Fortran 90/95 (F9X in the remainder of this review)

This however is also its main weakness: Even though F9X can be forced into these concepts, using those concepts, especially the proposed polymorphism method, is a tedious task, and makes a lot of the magic of OO programming disappear.

What is lacking in this book is an explicit overview of concepts which cannot be implemented easily in F9X, such as destructors, interfaces and inheritance, as that might be reason enough to forget about trying to implement your program in F9X.

My main conclusion after reading this is that trying to do OO in F9X is incomplete and way too much trouble, and thus the need for this book is rather limited.
