I have started reading Wired Magazine again, mostly because the quality of the articles has increased and the number of advertisements has decreased. Wired has a list of books that are similar to Smart Mobs. Related books include:
Digital Biology by Peter J. Bentley, 2001
Beyond Chaos by Mark Ward, 2001
Emergence by Steven Johnson, 2001
The Moment of Complexity by Mark Taylor, 2001
Linked by Albert-László Barabási, 2002
Nexus by Mark Buchanan, 2002
The Tipping Point by Malcolm Gladwell, 2000
Six Degrees by Duncan J. Watts, 2002
The Wired article summarizes the main contribution of each book. The general theme is that the role of the connections between objects in emerging networks can account for everything. Remember back to dynamic systems, differential equations and probability, no, well these are the basis along with biology for a new generation of patterns and ideas.
