Abstract:
     The paper contains a catalog of all known quasi-stellar objects
  (QSOs) with measured emission redshifts, and BL Lac objects, complete
  to 1992 December 31.  The catalog contains 7315 objects, nearly all
  QSOs including about 90 BL Lac objects.  The catalog and references
  contain extensive information on names, positions, magnitudes, colors,
  emission-line redshifts, absorption, variability, polarization, and
  X-ray, radio, and infrared data.  A key in the form of subsidiary
  tables enables the reader to relate the name of a given object to its
  coordinate name, which is used throughout the compilation.
     Plots of the Hubble diagram, the apparent magnitude distribution,
  the emission redshift distribution, and the distribution of the QSOs on
  the sky are also given.
