UC Berkeley professor Marc Trachtenberg is one of my favourite historians. His personal site has links to academic articles, declassification protocols, and advice on source analysis. Trachtenberg’s new book The Cold War and After: History, Theory and the Logic of International Politics (Princeton: Princeton University Press, 2012) looks like it will soon be added to my in-progress PhD methods chapter. You can read Chapter One: ‘The Question of Realism: An Historian’s View’ (PDF).
