A distribution of galaxies across the whole sky is presented based on the northern Morphological Catalogue of Galaxies (Vorontsov-Veliaminov and Krasnogorskaya, 1962; Vorontsov-Veliaminov and Archipova, 1963-1968), MCG, and the southern ESO B catalog (Laubers, 1982), and properties of the MCG are contrasted with those of both the ESO B and the northern Uppsala General Catalogue of Galaxies (Nilson, 1973). The final whole-sky catalog, containing 34,729 discrete galaxies, is approximately complete to a defined size limit rather than to a magnitude limit, and it is illustrated in a variety of equal-area projections to facilitate comparison with other work. Previously noted large-scale features such as the strong concentration around the supergalactic equator are visible.
