Publishers continue to react to the slow sales of illustrated titles. Following the downsizings at Harry Abrams and Rizzoli, Penguin Putnam is scaling back its Viking Studio imprint. Editor-in-chief Christopher Sweet is now serving as a consulting editor to the imprint, and editor Cyril Nelson has retired. A spokesperson said Viking Studio will continue to publish a limited number of titles annually. Viking Studio will now fall under the umbrella of Adrian Zackheim's new imprint.
