We have assembled a catalog of radial velocities and magnitudes on a homogeneous system (the corrected Harvard, B(o) magnitudes of de Vaucouleurs) for over 4000 galaxies. Using this catalog, we have compiled a magnitude limited sample of ~ 1000 galaxies with nearly complete radial velocity data. the magnitude limit is 13.0 and the galaxies are primarily from the Shapley-Ames catalog plus a few low and high surface brightness objects properly included in a magnitude limited sample. My colleagues, M. Davis, M. Geller and I are presently analyzing the dynamical properties of this sample. I would like to briefly describe a new determination of the field luminosity function and density plus our initial experiments with the use of a redshift catalog to select groups of galaxies.
