The Automated Retrieval Center (ARC), which opened in 2018, will be capable of holding up to 1.25 million volumes of the library’s print collection, placed in bins inside racks three stories high, with retrieval by robotic cranes. Currently there are about 550,000 volumes in the ARC. Placing the volumes in the ARC opens up more “stack” space to create areas for students to study and work together.
