The QUALCAT project at the University of Bradford attempted to apply automated quality control to databases of bibliographic records. Sets of records, putative duplicates, that appeared to be for the same monograph were grouped together and an expert system used to determine whether they were in fact duplicates, and if so which were the best records. This paper outlines the expert system used and discusses problems and further developments in automated examination of bibliographic records.
