Abstract
This is a review of Glauber's asymptotic diffraction theory, in which diffractive scattering is described in terms of interference between semiclassical amplitudes, resulting from a stationary-phase approximation. Typically two such amplitudes are sufficient to accurately describe elastic scattering, but the stationary points are located at complex values of the impact parameter. Their separation controls the interference pattern, and their offsets from the real axis determine the overall fall-off with momentum transfer. Asymptotically, at large momentum transfers, the stationary points move towards singularities of the profile function. I also include some reminiscences from our collaboration.

Report
I have attached an annotated version of the pdf of the paper in which I have made a few minor corrections, which I am sure the author can address and deal with swiftly. On the whole this paper is in excellent shape.
NOTE I HAVE TEMPORARILY TAKEN OUT TWO PAGES CONTAINING IMAGES (ON WHOICH I HAD NO COMMENTS) AND REDUCED QUALITY OF FILE SO THAT IT FITS INTO THE 1.2MB LIMIT TO UPLOAD HERE.
Requested changes
1- a few suggested alternative words shown in marked up doc
2- request for possibility of a reference or a link at the very end (as marked)
3- just one typo.
