Irwin Library

[1] Minoru Yamasaki was the lead architect, and constructed the library in the architectural style of New Formalism.

The library was named in honor of William G. Irwin,[4] who served as a trustee of Butler University from 1908 until his death in 1943.

[7] Butler University's third library, the Education Resource Library, serves the College of Education by providing access to children’s, young adult, curricular, and professional resources.

[8] In 2021, a six-person panel of American Institute of Architects (AIA) Indianapolis members identified Irwin Library among the ten most "architecturally significant" buildings completed in the city since World War II.

[11] Irwin Library features study rooms for individuals and groups that can be used for up to four hours at a time.
