Joan Didion, who died last week at the age of 87, helped shape a highly personal brand of nonfiction that came to be known as the New Journalism. Her early essay collections "Slouching Towards Bethlehem" (1968) and "The White Album" (1979) influenced generations of writers. Her later memoirs, "The Year of Magical Thinking" and "Blue Nights," chronicled the deaths of her husband and daughter. In 2011 Didion talked with Steve Paulson about illness and growing old in the wake of the death of her daughter, Quintana.
