The Book Mobiles travel in five clusters during the summer: Berkmar, Central Gwinnett, Discovery, Meadowcreek, and Norcross. The summer program operates for eight weeks in June and July with 90 stops each week. An average of 12,000 books are checked out each summer of the program.  

The books on the Book Mobiles are available for checkout in June and July each year. The books are selected by certified media personnel from the Media Service Department and reviewed by two media specialists at each level from clusters served by the summer program.
