Two degrees of separation in complex food webs
Feeding relationships can cause invasions, extirpations, and population fluctuations of a species to dramatically affect other species within a variety of natural habitats. Empirical evidence suggests that such strong effects rarely propagate through food webs more than three links away from the initial perturbation.
Synchronization in small-world systems
We quantify the dynamical implications of the small-world phenomenon. We consider the generic synchronization of oscillator networks of arbitrary topology, and link the linear stability of the synchronous state to an algebraic condition of the Laplacian of the graph. We show numerically that the addition of random shortcuts produces improved network synchronizability.
Lecture 11: Graph Structure of the Web
Two interesting points: 1. The seed set for AltaVista must be at least 10 million (actually, presumably, much larger). Creating a huge seed set almost as important as crawling.2. How on earth does AltaVista find URLs for 10 million isolated pages?

Books on Scale-Free Network
A network that is scale-free will have the same properties no matter what the number of its nodes is. Their defining characteristic is that their degree distribution follows the Yule-Simon distribution — a power law relationship.Here is a pool of best book on Scale-free network.

The Self-Organization
Self-organization is a process of attraction and repulsion in which the internal organization of a system, normally an open system, increases in complexity without being guided or managed by an outside source. Self-organizing systems typically (though not always) display emergent properties.
