Despite the immense research Doctorow needed to create stories based on real events and real characters, reviewer John Brooks notes that they were nevertheless "alive enough never to smell the research in old newspaper files that they must have required". Doctorow demonstrated in most of his novels "that the past is very much alive, but that it's not easily accessed," writes Parini. "We tell and retell stories, and these stories illuminate our daily lives. He showed us again and again that our past is our present, and that those not willing to grapple with 'what happened' will be condemned to repeat its worst errors."
