| Sumario: | Alternative methods of ranking journals based on citation data are examined. The techniques of Data Envelopment Analysis and, to a more limited degree, integer programming, have been applied, whereby each journal is permitted to select its preferred weighting scheme so as to maximize either its “efficiency” score or its ranking. Despite the limitations of this type of analysis, the approach seems to be preferable to that employed by Diamond (1989) in that it systematically allows for multiple measures of performance. The results of the 1986 citations data reveal that although many of the journals in the Diamond list of core journals reappear, there are a number of changes, most noticeably the inclusion of some economic history journals. The comparison of the 1986 citations data with those of 1991 suggests that the set of journals that can rank themselves in the top ten is reasonably stable. However, it would seem that many other journals may be able to place themselves in the set of top 27 journals at different times.
