Under a restriction for minimum angular diameter of not less than 1 arcmin, corresponding to the 15th magnitude and allowing morphological classification of structure, 16,000 galaxies have been brought together in the single volume of the ESO/Uppsala catalog (1982). Attention is given to the automatic parameter extraction methods employed, and detailed information is presented for preliminary results on test field No. 358, which covers the Fornax cluster. The data for the 70 galaxies in this test field yield results which are of general interest, such as estimates of total magnitude from a combination of major and minor diameters that yields angular size.
