The designer was Edward Durrell Stone who followed recommendations by a Boston library consultant who recommended that the University would require a building of nearly 310,000 square feet to meet with the growing demands of students. Ground was broken in April 1969 and the building was opened to the public in 1973, with an official dedication taking place in 1974.
