Just in case there weren't enough book related events to keep you busy this weekend. The publishing industry's three day extravaganza, The Book Expo, is being held at Mccormick Place over the next few days. The event kicks off tonight with a keynote address from former President Bill Clinton. There will be more than 2,000 exhibitors, 500 authors and over 100 conference sessions. Some of the highlights include appearances by Art Speigelman, Amy Tan and David Sedaris. Unfortunately the event is open only to industry professionals.
