Source Material

These are my two primary sources, An Exorcist Tells His Story by Gabriele Amorth (one of the leading exorcists in Rome), and The Making of a Modern Exorcist by Matt Baglio, both of which I highly recommend.  There is a bit of overlap, as Mr. Baglio also uses Father Amorth as a source.  Other books I've read on the subject include More Stories by Father Amorth, and Hostage to the Devil by Malachi Martin.  Hopefully I can broaden my library soon.
