Featured on The Discovery Channel, ISU’s Williams Hall is considered to have paranormal activity going on daily. Williams Hall was the first library on ISU’s campus when it was first built and the first librarians name was Angie Milner. There have been sightings of a full body apparition and also strange stories and occurrences that have happened to staff as well as students. The library was investigated and showed proof of spiritual energy. This building has made it onto the “Haunted Places in Illinois” list and also proves that paranormal activity is within Bloomington-Normal. This is a very mysterious and interesting place, but also is a main attraction for people who seek the thrill of the paranormal.

Angie Milner was also the inspiration for the Librarian ghost in the movie "Ghostbusters".
