The 100-year-old Phoenixville Library has long been rumored to be haunted by ghosts of a man and his dog.
Now, some local Ghosthunters think they have evidence proving the library has paranormal patrons.
Librarians at the facility say the old man has been getting cranky lately. And real-life ghost hunters say they have the proof.
"Books have been sliding off the shelf," said librarian Dorothy Wolff. She also has seen a spinning pencil holder.
Lots of other employees have apparently seen the ghosts and over the weekend, the library brought in the Chester County Paranormal Research Society - volunteer Ghostbusters if you will.
Their ghost-energy testing equipment went nuts in the old building, and a night surveillance camera caught a book flying off a shelf.
All of this is leading to a serious question: Could this place really be haunted?
"Oh yeah definitely," says Cindy Starr-Witman of Chester County Paranormal Research Society. "Hair is standing up on your arm or the back of your neck - (you are) feeling chills with the temperature dropping suddenly several degrees."
This expert says these ghosts are harmless and readers should keep on coming to the library.
"They don't have anything to fear," says Starr-Witman. "It's nothing that's going to hurt them or harm them in any way."
If you want further proof, the local Ghostbusters and even the town newspaper caught mysterious lights on camera at the library.
