The Willard Library in Evansville, Indiana, they say, is haunted by "the Gray Lady." The apparition was first seen in 1937 when the library's janitor caught a glimpse of the veiled spectre in the basement. Since then, several other staff members have seen the ghost, smelled the scent of her perfume, and on numerous occasions turned off faucets that the spirit had turned on. Many believe the ghost is that of Louise Carpenter, the daughter of the library's founder. This site has three webcams, one in the research room
