Pazuzu Manifestation here on ManyBooks appears to be the old Third Revision, I've been trying to get this copy updated with the latest Eighth Revision without luck.

Eighth Revision reads like a totally new book - a lot of work has gone into cleaning the typos and errors and smoothing the pace. This is a fast introduction to the Shur desert and its cursed inhabitants - the story peaks in the second book Pazuzu - Emergence.
