I listened to an interview with Dan Aykroyd tonight and he said something that I thought you guys might find useful.
He strongly recommended the book, "Ghosts" by Hans Holzer. So I looked it up. Here's the blurb from the back cover:
"
Take a journey to the world beyond...
- Visit hundreds of haunted places around the world,
- Learn how to make contact with "the other side."
- Read about ghostly manifestations of all kinds, from phantoms to poltergeists—and learn about the scientific investigations that have uncovered and authenticated them.
- See rare, genuine photographs of ghosts and spirits, and find out how these apparitions were captured on film.
Travel to all corners of the world in search of ghosts with Dr. Hans Holzer, one of the world's foremost experts on the subject and the author of more than 100 books on parapsychology, the supernatural, and the paranormal phenomena. Not only does Dr. Holzer introduce us to those who visit from the next dimension, he explains why they seek contact with our world and he offers expert advice on how to interpret sights, sounds, activities, visions and other experiences that signal the presence of someone from the other side. Ghosts is a must-read for all would-be ghost hunters and fans of the otherworldly."
It is 768 pages long. This really sounds like the inspiration for Tobin's to me, or at the very least a place to look for inspiration.
