So, for Pentecostals, this is kind of one of those "must have" items. Bartleman's work is one of the most significant, first-hand accounts of one of the most important moments in church history. Whether you are Pentecostal or not, the formative role of the Azusa Street revival on the church, worldwide, of today is impossible to ignore. This work very sought by collectors and historians.

Please note, while it is marked "Second Edition," it is technically, in modern terms, the Second Printing of the First Edition.

Good + to very good.
