Scientific paper

We present the third major update of new optical and radio data for the strong sources in the Revised Third Cambridge Catalogue (hereafter 3CR). New positions, redshifts, magnitudes, and identifications have been included as well as some radio data for the sample of 298 extragalactic 3CR sources. A new and extended bibliography of optical and radio data is included. The 3CR sources have now reached an almost satisfactory state of optical identification; 91% of the sources at ∣b∣ > 10° now have firm identifications and we have spectra for most of them. The few remaining faint objects at high latitudes are, of course, important, as they tend to be the most luminous radio sources known. Full completion of the 3CR data will aid in reducing the residual uncertainties at the luminous end of the evolving radio luminosity ftinction. Finally, we present some new identifications and new spectroscopic data for 29 faint 3CR galaxies, and one quasar.
