Tobin's Spirit Guide by Kim Mohan is a source book for the Ghostbusters Role-Playing Game. It is based on a reference book on various spirits mentioned in the movie, and is written as if it actually was the book mentioned, albeit a "slightly edited and slightly supplemented version" based on the first edition as recovered and reprinted by Dr. Stantz.
The book contains numerous ghosts and other supernatural beings for players to encounter throughout the game, divided by geographic region into four chapters: Egypt and Asia; Great Britain and Western Europe; Eastern Europe; and Eastern America. It also includes optional rules for variable Ectopresence based on an entity's proximity to a goal or an important focal point.
The full title is written as, "J.H. Tobin's Spirit Guide BEING A COMPENDIUM of Ghosts, Gods, Spirits, and Manifestations from Outside the Normal Realms of Existence, ~ WITH A TRAVELOGUE and Notes on a Philosophy of the Occult - Established by the Author -"
