The Gospel of John and Christian Origins.”  Looks interesting, I shall add to my list….

The author of this fine volume, John Ashton, has written a couple of studies on the fourth Gospel, including Understanding the Fourth Gospel (Oxford University Press, 1991; 2nd ed. 2007) and Studying John: Approaches to the Fourth Gospel (Oxford University Press, 1998). http://goo.gl/KnrCdX
