Nebular abundances of southern symbiotic stars
We have calculated relative element abundances for a sample of 43symbiotic stars. Helium abundances and the relative elemental abundancesN/O, Ne/O, Ar/O were derived from new spectra collected in the opticalrange through low dispersion spectroscopy. The He ionic abundances werederived taking into account self-absorption effects in Balmer lines. Wefound that the symbiotic stars in the galactic bulge have heavy elementabundances showing the same wide distribution as other bulge objects. Inthe galactic disk, the symbiotic stars follow the abundance gradient asderived from different kinds of objects.

BVR Photometry of Northern Hemisphere Luminous Stars. III. LS and HD Stars
CCD-based BVR photometry of 48 previously unobserved stars drawn fromvolumes V and VI of the Luminous Stars in the Northern Milky Way,Luminous Stars in the Southern Milky Way, and HD catalogs is reported.

UBV beta Database for Case-Hamburg Northern and Southern Luminous Stars
A database of photoelectric UBV beta photometry for stars listed in theCase-Hamburg northern and southern Milky Way luminous stars surveys hasbeen compiled from the original research literature. Consisting of over16,000 observations of some 7300 stars from over 500 sources, thisdatabase constitutes the most complete compilation of such photometryavailable for intrinsically luminous stars around the Galactic plane.Over 5000 stars listed in the Case-Hamburg surveys still lackfundamental photometric data.

A spectroscopic database for Stephenson-Sanduleak Southern Luminous Stars
A database of published spectral classifications for objects in theStepenson-Sanduleak Luminous Stars in the Southern Milky Way catalog hasbeen compiled from the literature. A total of 6182 classifications for2562 stars from 139 sources are incorporated.
