Organizations rise and fall. In between, they change-sometimes negligibly, sometimes gradually, sometimes radically. For the scholar who is interested in understanding the latest thinking on organizational evolution and change, this book is critically important. It presents fresh, insightful pieces from many of the leading thinkers on the topic. We can expect to find the Baum and Singh volume on a lot of desks, and represented in many reference lists, through the rest of the 90's. Donald C. Hambrick, Columbia University
