The thirteenth largest university library in North America, IU's Herman B Wells Library serves as an excellent academic resource for all students. Built in 1969, the building contains 11 floors in the graduate tower and five floors in the undergraduate tower. The building also contains the Information Commons, a fully-integrated technology center for learning and collaboration -- open 24 hours a day, seven days a week.

The Herman B Wells Library (known as the Main Library until April 2005) houses the core of the university's research collections. The building is also home to the School of Library and Information Science (SLIS).
