Abstract
CCD observations and B, K, and R photometry of the 178 radio sources in
the Parkes Selected Regions survey are presented. Recent spectroscopic
observations are shown to increase the redshift content to 46 percent,
including all the quasar candidates. It is suggested that not more than
10 of the present objects can lie at z of greater than 2.5. The present
results are used to constrain the high-redshift cut-off in the radio
luminosity function and to provide new information on the optical
spectral evolution of radio galaxies.
