Radio observations of 4079 quasars

Using the NVSS radio catalog, we have searched for radioemission from 4079 quasars taken from the 1996 version of the Veron-Cetty & Veron [ESO Scientific Report No. X (1996)] quasar catalog. The comparison resulted in the positive detection of radio emission from 799 quasars. Of these, 168 are new radio detections. Examination of the radio luminosities shows a dramatic increase in the fraction of radio-loud quasars from the current epoch to z=0.5 and a gradual decline beyond z=1.0. Inspection of the radio-loud fraction as a function of M-B shows little dependence fainter than M-B=-29.5. (C) 1997 American Astronomical Society.
