Robert Morin had his quirks: a regular breakfast of Fritos and a Coke; a refusal to give up on the 1992 Plymouth that he drove to his job as a library cataloger; the 18-year span, from 1979 to 1997, during which he watched more than 22,000 movies — an average of about three a day. Morin read in chronological order every book published in the United States between 1930 and 1938, excepting only textbooks, children’s books and cookbooks.
