The Best of NPR: Biography ∧ Autobiography (90 minutes) brings back five provocative interviews with the biographers of some of this century's most inspiring, complicated, and enigmatic characters; Edmund Morris on Ronald Reagan, Stephen Ambrose on Richard Nixon, James Gleick on Richard Feynman, Otto Friedrich on Glenn Gould, Peter Guralnick on Elvis Presley, and five authors on the special challenges of autobiography, including Frank McCourt, Mary Karr, Cyra McFadden, James McBride and the elusive M.F.K. Fisher. These short segments are just long enough to whet your appetite and remind you how very good National Public Radio can be. (Proceeds support NPR programming.) Reviewed by Sukey Howard.
