Its full title is: Chess 4.5: The Northwestern University Chess Program by David Slate and Larry Atkin. It was first published in Peter Frey's excellent, but now very outdated, book "Chess Skill in Man and Machine" (Springer-Verlag, New York, 1977), pages 82-118. It is also reprinted in David Levy's "Computer Chess Compendium" (Batsford, London 1988). The section of the paper that is relavent is the part entitled "mop-up evaluation". I think you will find the rest of the paper very interesting as well: they describe their general evaluation function in great detail, as well as their implementation of the recursive alpha-beta algorithm with various refinements that are nowadays, however, quite commonplace. Their program was of some historic interest, being as far as I know the first efficient bute force searching program to play to a high standard in tournaments. Best wishes, Roberto
