I got my new copy of Professor Bailyn's Ideological Origins in the mail on Halloween. The copy I bought was the fiftieth anniversary edition with a commensurate introduction by the author. Neat to read an author's notes re-reading his own book after half a century. "What strikes me now...", "Looking back at the result now...", "I can now see more clearly than before..." It is a treasure. Professor Bailyn is a treasure.
