David Easley and Jon Kleinberg have a textbook coming out called Networks, Crowds, and Markets: Reasoning About a Highly Connected World. It looks great, and for now you can download a preprint of the whole thing for free. Cornell, home of founding co-blogger Matthew Brashears seems like a great place to do work on networks.
Robert Hanneman (with coauthors Riddle and Izquierdo) also has a free textbook or three for you to download. I won’t try to summarize any of these books since you are just a click away from viewing them, but I will point out that they aren’t competitors… they each have a lot of unique material.
