Linked: The New Science of Networks

Barabási's book introduced the science of networks to a popular audience: scale-free networks, preferential attachment, hubs, the small-world property, and the mathematics that explains why the internet, social networks, disease transmission and cellular metabolism share the same structural patterns. The book is the accessible version of research that reshaped how we understand interconnected systems. For product direction the frameworks are directly applicable — platform dynamics, viral growth, network effects, and the vulnerability of systems with concentrated hubs are all applied network science. Read alongside Castells for the sociological layer and Shapiro and Varian for the economic implications. Barabási writes clearly; the science has aged well.
