Greencastle also once had a municipal Carnegie library, which is now known as The William Weston Clarke Emison Museum of Art (otherwise known as The Emison Museum of Art or The Emison Art Center). The library became a museum in 1986, and was renamed to honor the financial contributions of James W. Emison, a longtime member of DePauw University's Board of Trustees and benefactor of the University, and other Emison family members. The building was constructed in 1908. The Emison Art Center was originally the Depauw University (then, Indiana Asbury University) campus library.
