Alcoholics Anonymous has thrived until recently without benefit of publicity save by word of mouth. Indeed, one of its tenets (humility) and its avoidance of any organizational set-up have not made ""public relations"" a congenial function. But this is the third book dealing with this unique movement to appear in the last six months. It is written by a Protestant minister who has worked very closely with A. A. and is intimately acquainted with its working principles and procedures. The author is concerned primarily to discover why A. A. has been successful in rescuing chronic alcoholics while the church has so largely failed in so doing. He is also concerned to make plain the religious basis of A. A. wherein it differs from the Christianity of the churches. His is a very appreciative account of the working of A. A. and he believes that the church has much to learn from it not only in dealing with alcoholics but in approaching all human problems. On the other hand, he makes clear that the religious experience provided by A. A. is not a substitute for the fellowship of the church.
