Groundbreaking for the new library building at Fairfield University took place in 1967 and opened the following year. The new building was planned with an estimated 20 years worth of space to grow. With the opening of the new building in 1968, the library increased its capacity from 90,000 books to 300,000 books. It featured a smoking area, two typing rooms, and its first full-time reference librarian. In 1971, the library was named Nyselius Library in honor of benefactors Gustav and Dagmar Nyselius. The library received numerous incremental updates throughout the years, including the opening of a computer lab and media department, before a large expansion and renovation project in 1999 after receiving a significant donation from alum Joseph A. DiMenna, Jr. In the fall of 2001, the DiMenna–Nyselius Library opened.
