National Book Network has shut down its five-person publicity department. Designed to help its client publishers with their publicity efforts, the unit "was a strategic mistake," NBN president Jed Lyons said. He noted that it was hard to gauge the effectiveness of individual campaigns, a situation that sometimes led to friction between NBN and its clients over just how well a publicity program worked. Carole Juarez, former director of the publicity department, has established her own firm and will be handling publicity for a number of NBN clients.
