The writings of Isaiah Berlin (1909–1997), now published chiefly by Princeton University Press, have in large part been brought to light thanks to the work—over five decades—of Henry Hardy. A Fellow of Wolfson College, Oxford, Hardy discusses Berlin’s life, work, and thoughts. Hardy maintains The Isaiah Berlin Virtual Library (link). Selections from Berlin on Karl Marx were republished in Econ Journal Watch in September 2025 (here and here). Hardy’s book In Search of Isaiah Berlin: A Literary Adventure (2018, Amazon link) tells of his own interaction with Berlin and his writings.
