This catalog is intended to list all galactic S stars having known positions of at least roughly the precision of the Henry Draper catalog. The first edition of this catalog, published more than eight years ago, contained little more than half of the present number of stars, but nearly half of those were previously unpublished although lists of Henize's discoveries had been widely circulated. The principal additions since then come from three sources: (1) A low-dispersion infrared survey of the southern Milky Way by Westerlund, the S stars from which are hitherto unpublished; (2) a relatively high-dispersion red survey by MacConnell, also for the southern Milky Way, published in two lists here catalog-coded as MacCon79 and MacCon82; and (3) an unpublished and just-completed intermediate-dispersion red survey by the author, covering the sky north of declination -25° and outside of galactic latitudes ±10°.
