I will present recent results from a complete sample of
galaxies which are both radio sources in the 1.4 GHz NRAO
VLA Sky Survey (NVSS) and X-ray sources in the ROSAT All-Sky
Survey Bright Source Catalog (BSC). These catalogues were
cross-identified using a technique akin to the likelihood
ratio. This sample of \approx1500 objects is composed of
nearly normal galaxies, Seyferts, quasars, and clusters with
an average redshift of \approx0.1. The dominant
population is active nuclei, ranging from local low
luminosity AGN out to distant QSO's and BL Lacs. I have
obtained redshifts and classifications for a
magnitude-limited (J \leq 18 and \delta \ge -20\deg)
subsample. The spectra permit a calculation of multivariate
radio-X-ray-optical luminosity functions of these local
galaxies and model evolutionary effects as a function of
classification type. The sample has statistically
significant numbers to probe a variety of classes and
investigate nearby low lumninosity objects.
