Conceived and edited by film director Martin Bell, Mary Ellen Mark’s husband and collaborator for over 30 years, The Book of Everything celebrates in over 600 images and diverse texts Mark’s extraordinary life, work and vision. From 1963 to her death in 2015, Mark told brilliant, intimate, provocative stories of remarkable characters whom she would meet and then engage with―often in perpetuity. There was nothing casual or unprepared about Mark’s approach; she unfailingly empathized with the people and places she photographed. For this comprehensive book Bell has selected images from Mark’s thousands of contact sheets and chromes―from over two million frames in total.
