Four major improvements have been made in the ZRD – SEARCH – MATCH program [Frevel (1965), Anal. Chem . 37 , 471–482]; namely, (1) restriction of the file of standards to the 298 most frequently encountered phases, (2) utilization of a single index file based on the most intense reflection, (3) incorporation of a novel search function, and (4) revision of the quantitative matching of powder patterns.
