Organizational Ecology is an exceptional book. It is at several points an exemplar of integrating formal theory with sophisticated empirical research… The future will look back to…the period when theory emerged to formalize the temporal component in the relationship between competition and formal organization. The key book in that long look back will be Hannan and Freeman’s Organizational Ecology. This is a book in which we can all take pride as sociologists.
