This bibliography is a continuation of those published by Berry and Daniel (1984, 1985), Daniel (1981a, 1981b), Fulkerson and Wise (1987, 1990, 1992), Fulkerson, Wise, and Ancelet (1988), Johnson and Daniel (1974), Morgan and Daniel (1983), Mosely and Daniel (1982), and Wise and Fulkerson (1986, 1989, 1991). Search methods, criteria for inclusion, and other considerations were similar to those used previously. We have also continued the cumulative numbering practice of previous bibliographies. We included some pre-1992 citations not listed in previous bibliographies because we continue to terminate our search in June.
