We are pleased to announce that, in this fiftieth anniversary year of American Heritage , one of our favorite books has come back into print. A Sense of History , originally published in 1985, is an anthology of articles that together form a lively, unorthodox history of doings on our continent from the rise of the dinosaurs to the fall of Richard Nixon. iBooks has just reissued the book, augmenting the original text with a provocative fortieth-anniversary poll of how the nation had changed since the magazine first came into being, and a new introduction by James McPherson (848 pages, $29.95).
