Libertarianism.org – Finally! A non-technical, one-stop shop for the major ideas in the philosophical tradition of liberty. Cato Institute project.
Governance Without a State: Policies and Politics in Areas of Limited Statehood (Columbia UP) – File under “order in anarchy.” Mostly European scholars giving somewhat different takes than you get with the UK-US “economics of anarchy” research. Nothing blindingly new to students of Olson, Ostrom, and Axelrod, and many of the contributions simply address political economy issues in developing countries, not “failed states” or “anarchies” strictly defined, but the chapters by Schuppert and Chojnacki & Branovic are worth reading.
