1982 D. M e a d o w s , J . R i c h a r d s o n a n d G. B r u c k m a n n : G r o p i n g in the D a r k : T h e F i r s t D e c a d e of G l o b a l M o d e l l i n g . John W i l e y a n d Sons Ltd., 1982, 311 pages, £11.00, I S B N 0-471-10027-7. This b o o k is b a s e d on the p r o c e e d i n g s of the Sixth I I A S A S y m p o s i u m on G l o b a l M o d e l i n g . It is a real life history of global modeling. It is conc e r n e d with the m a j o r m o d e l s a n d those w h o m a k e them. A feature is the honesty, the c a n d o u r a n d the clarity with which the a u t h o r s discuss w h a t global modeling thaught them about modeling and a b o u t the world. It could be d e s c r i b e d as a b o o k o n the sociology o f a new science struggling with p r o b l e m s too large for the p a r t i c i p a n t s , b u t too i m p o r t a n t to be ignored. This b o o k written in a very original f o r m a t is specially m e a n t for those who m a k e c o m p l e x m o d els of c o m p l e x social systems, for those w h o m a k e these systems work, a n d for those who live in a n d c a r e a b o u t the social systems that modellers m a k e a n d a b o u t which decision m a k e r s m a k e decisions.

of chapter five, while chapter six deals with support languages for model simulation. Chapter seven considers the hardware tools and their impact in simulation. Finally, chapter eight reports on simulation systems and architecture arising from methodological research. The literature in the area of modelling and simulation has previously been fragmented in a number of publications. This volume attempts a real synthesis of the field. Moreover, it is probably one of the first to address all important issues that

follow from a partnership between man and machine. Scientist and engineers with a basic knowledge of mathematics, including linear algebra and differential calculus, will find this an extremely useful guide to computer-aided modelling and simulation techniques. Applied mathematicians and computer scientists will also find here much interesting material and many suggestions for future research.
