NEW YORK -- Genevieve Young was a publishing editor with a long and diverse legacy.She entered the business in the early 1950s, when there were few female editors and even fewer Asians. She worked with authors ranging from Herman Wouk to Betty Rollin and played a key role in the writing of Erich Segal's “Love Story,” the novelization of the Oscar-winning movie of the same name that is currently marking its 50th anniversary.
