Book excerpt: In 2001, photographer Thomas Roma was given access to the addresses of the patients of William Carlos Williams - successful doctor and legendary poet in the 1940s and 50s. These addresses were plotted on a map, becoming the route that Roma travelled and recorded over the next five years, retracing Williams' footsteps from decades past. Dr Williams would travel from Rutherford, New Jersey to Paterson, New Jersey, stopping to attend to his patients en route. Roma's photographic re-treading of this journey is an immersive experience.
