A recent compilation of globular cluster data (Harris, 1991) has been examined for the purpose of s electing a sufficiently large set of globular clusters with reliable distance estimates. The absolute differences between recent and past estimates of the cluster parameters V(HB) and E(B-V) have been studied in statistically representative (but not mutually exclusive) subsets; resulting in a conservative estimate of the average distance modulus error of 0.40 m for a total selected sample of 134 objects. The effects of spatial and metallicity segregation on the statistics of this sample are investigated. The adopted distance scale uses consistent correction terms for metallicity and reddening according to the precepts in Racine & Harris (1989). From a direct comparison with the spatial configuration of clusters derived in the past, random observational errors are shown to dominate the uncertainties in locating the clusters along their lines of sight.
