|Tobin's Spirit Guide|
Book on the Supernatural
The Real Ghostbusters,
Ghostbusters: The Video Game
Tobin's Spirit Guide  by John Horace Tobin is a book that serves as a compilation of various supernatural occurrences, entities, and facts. The computer software version is hard to find and is very expensive. Egon and Ray refer to it so frequently they may have entire sections memorized. Copies of the book have been shown to be available in hardback, paperback, and electronic media. Tobin's Spirit Guide often helps the Ghostbusters with identifying entities involved in the cases that they take on.
As Ivo Shandor is mentioned in the tome, it is reasonable to assume Tobin's Spirit Guide was written sometime in the 20th Century. Gozer rituals have been recorded in the book as happening as early as the 1920s so the guide would have to have been published anywhere from 1930-1980.
The Spirit Guide is used extensively in Ghostbusters: The Video Game. Here, the player can use the P.K.E. Meter to scan ghosts and objects, unlocking their entry in an electronic version of the guide. In the Stylized version, Art Pages can also be found, which add images to the guide entries. The original manuscript can also be found in the basement of the firehouse in the Stylized version. In the Realistic version, once a ghost is scanned, a complete bio of the ghost appears, complete with a picture, their class level, their powers, the ghostbusting weapons they are weak against, whether they can be trapped or destroyed, and some information on their back story. Scanning and obtaining the Spirit Guide entries of any ghost in the game will unlock an Xbox 360 Achievement or PlayStation Trophy called "I'm Picking Up A Signal...," while obtaining the entries of all ghosts will unlock "Back Off Man. I'm a Scientist."
The Real Ghostbusters
In The Real Ghostbusters, Egon and Ray shown to carry around a paperback version of the book on assignments. Egon sometimes had Tobin's Spirit Guide on small computer interface devices and later on computer. The latter was noted as being very expensive by Ray, because it probably wasn't popular to which Egon scoffs. It is also shown that the Ghostbusters may not have read every entry, as they often find something new when looking up unknown spirits in the guide. In Extreme Ghostbusters, the team uses Spengler's Spirit Guide, which may borrow material from Tobin's Spirit Guide. It may even be a complete rewrite of Tobin's in Egon's own words. However, the Extreme Team appear to rely more on the internet and checking out books to dig up information on ghosts that they know little about (though a copy of Tobin's can be seen on Egon's desk in the first episode).
It was published as a source book for the Ghostbusters Role-Playing Game, containing ghosts from all over the world that could be used as adversaries in the game. As well as some background on Tobin himself.
In the IDW Comics continuity, the Paranormal Contracts Oversight Commission keeps a file on Tobin's Spirit Guide, #SG1a. A hardcover copy of Tobin's Spirit Guide was taken aboard a flight to Schenectady by the Ghostbusters. Ray and Egon consulted it while trying to narrow down the identity of the entity they were sent off to confront. In mid-September 1912, Tobin documented his travels in Siberia in the guide.
In the present, Ray Stantz and Kylie Griffin used Tobin's Spirit Guide for their research on instances of recurrent child hauntings and supernatural abductions in the last 50 years. There are pages on Tiamat and Gozer in succession. Both have depictions of one of their known forms and entries are written in Gozerian Alphabet. There also pages that detail the rules that bound Gozer. Gozerian imagery and hieroglyphics are included on these pages. An annotated copy of Tobin's Spirit Guide is kept in Egon's foot locker.
