On February 2010 a bunch of network scholars (including me) convened in a workshop in USC (the Annenberg School) to talk about Network Theory. The strength of the workshop was in its ability to bring interdisciplinary perspectives about network theory to one table. The videos, powerpoints and reports of each one of the talks are available on the ANN (Annenberg Networks Network) website.
As a result, the IJoC (International Journal of Communication) dedicated a volume to network theory.
Here are the papers presented in that volume (they are fully accessible in the following links):
Prologue to the Special Section: Network Multidimensionality in the Digital Age by Manuel Castells, Peter Monge, Noshir Contractor
Introduction to the Workshop: The Promise of Network Theory by Manuel Castells
