Not to be confused with the real world book Ghosts from Our Past: Both Literally and Figuratively: The Study of the Paranormal released by Three Rivers Press.
A book written by both Erin and Abby before parting ways, the book was later released without Erin's permission. She found out about it by a meeting with Ed Mulgrave Jr.. She that day found out more about it on Amazon including where she could get a hold of Abby. She went to Kenneth P. Higgins Institute to visit and request the book be taken down. She went with Abby and Erin to the Aldridge Mansion Museum to introduce them to Ed in the hopes they remove the book from Amazon. Ultimately she went with them into the mansion and she had a direct interaction with the ghost, Gertrude Aldridge.
Several copies of the hardcover are still laying around in the Firehouse. During the dimensional overlap, Abby asked Kylie Griffin if Ray's Occult Books had her and Erin's book "Ghosts from Our Past" in stock. Kylie never heard of it. Abby figured as much.

Ghosts From Our Past: Both Literally and Figuratively: The Study of the Paranormal
By Abigail L. Yates & Erin Gilbert
Through all of history, societies have believed in the survival of personality after death. From ancient Mesopotamian spirits, to Pliny the Younger's letters, to modern encounters with apparitions, ghosts have an important place in human folklore. But are these stories just folklore, or can science give us definitive proof of their existence?
Ghosts From Our Past: Both Literally and Figuratively: A Study of the Paranormal is an exhaustive exploration of the marriage between paranormal research, physics, and science. Using particle physics, quantum theory and mathematics to examine case studies of real encounters with ghosts, Ghosts From Our Past offers an explanation for the things that, until now, could be explained.
Authors Abigail L. Yates and Erin Gilbert use scientific methodology to test traditional paranormal theories, while adding a new dimension in research to unlock the mysteries of the unseen worlds. Chapters include:
Pure Energy The Law of Conversation and the Afterlife
Something Weird The visible, Audible and Telepathic Experience
Schrodinger's Ghost The Observation Paradox and the Quantum System
Parallel University Quantum Fluctuation and Corresponding Particles
Ghostly Magnetism: Atmospheric, Electrical and Magnetic Clues
Erin Gilbert started her undergraduate work in Physics and Quantum Mechanics at University of Michigan. As an undergraduate she has coauthored the seminal paper "Condensed Matter in Transport of Fractional Quantum Hall States." She plans on finishing her graduate studies at MIT, under Professor Han Anschutz. She will also complete her Doctoral work at CERN and is currently studying Swiss.
