I report on results from the Arizona/New Mexico spectoscopic survey. This sample includes 1172 galaxies in five regions of the sky. The observations were made with the Steward Observatory 2.3 meter telescope and a reticon detector, providing spectral coverage for the whole optical window from 3600 to 7000 Angstroms. Continuum indices and line strengths are used to examine population differences between different superclusters. Among other results, I find that the surveyed portion of the Coma/A1367 supercluster is deficient in early type galaxies; this is probably consistent with the low galaxian density in the region. I also find morphological segregation and a bimodal position angle alignment in portions of the Perseus supercluster.
