The catalogs of bright galaxies (B_J<16.5) compiled from APM scans of UKST IIIa-J Sky Survey plates have now covered most of the southern sky (|b|>20(deg) ). This presentation reviews the current status of these catalogs, and the ongoing scientific research supported by them. In particular, the first results from the catalog of galaxies (B_J<17, D>0(') .5) compiled from the IIIa--J plates of the UKST Equatorial Survey are presented. This covers a part of the sky (-17(deg) < delta < -2(deg) , |b|>20(deg) ) that was not surveyed for the UGC and ESO catalogs, and hence is the first equivalent galaxy catalog in the Equatorial Sky. All galaxy candidates from a preliminary star-galaxy separation exercise were visually inspected, and the identified galaxies were assigned a morphological type. This catalog of over 50,000 galaxies from 200 plates lists accurate positions and shape parameters for all galaxies, together with their diameters and B_J magnitudes, measured by edge-matching and CCD calibration.
