Description:
    The Automated Quasar Detection (AQD) technique has been applied to six
    connected fields near the South Galactic Pole. A comparison with the
    Veron & Veron catalogue (1993) VII/188 and the Cristiani et al.
    compilation (1995A&AS..112..347C) shows that AQD rediscovered ∼75% of
    the known quasars with non-overlapping objective-prism spectra present
    in these fields (∼40% if considering only the high degree candidates).
    A list of 1592 high grade candidates is given, including the results
    of cross-correlation with X-ray and radio catalogues.
