Is 'Tobin’s Spirit Guide' From 'Ghostbusters' Real?

In times of difficulty the Ghostbusters often turn to one book to help them identify entities involved in haunting cases, that book was written by London-born John Horace Tobin and published in October 1920, but is 'Tobin's Spirit Guide' a real book?

J.H. Tobin's Spirit Guide was first mentioned in the 1984 'Ghostbusters' movie by Egon Spengler when discussing the 55 Central Park West building, "the architect's name was Ivo Shandor. I found it in Tobin's Spirit Guide. He was also a doctor. Performed a lot of unnecessary surgery. And then, in 1920, he started a secret society."

So, who was this Tobin? Well, it said he was born in London in the 1870s and after studying at Oxford University he went into middle management for British company based in Egypt where, in 1899, he encountered and Ahagotsu, an Egyptian spirit. After this he really became the first ever ghostbuster, he vowed to spend the rest of his life fighting paranormal being with his friend Shrewsbury Smith.

There are in fact two real life version of Tobin's Spirit Guide and both are available from Amazon (and probably all or some good book stores.)
