This volume makes a significant contribution to the crisis management literature. It also adds to our inchoate understanding of network governance: temporary teams and task forces, communities of practice, alliances, and virtual organizations. It hints that the distinction between networks and organizations may be somewhat spurious, a matter of degree rather than kind. Indeed, it seems that this distinction may derive more from mental models in which we consistently reify organizations than anything else. Finally, the volume emphasizes the functional importance of leadership in network governance and puzzles over its provision in the absence of hierarchy. As such, it adds to the contributions made by Marc Granovetter (1973), John Seeley Brown and Paul Duguid (1991), Bart Nooteboom (2000), Paul J. DiMaggio (2001), John Arquilla and David Ronfeldt (2001), Laurence Oâ€™Toole and Ken Meier (2004), and others, as well as Nancy Robertsâ€™ seminal work on wicked problems and hastily formed teams. The result is a product the editor and the contributors can be proud of. Overall, it is one that will edify, surprise, and delight its readers.
