Catalogue and Bibliography of Emission-Line Stars of Types Later than B.

This catalogue enumerates the known middle- and late-type emission-line stars and provides a comprehensive bibliography of the spectroscopic observations of these objects. A total of 1114 stars whose spectra show bright hydrogen lines is included, grouped into eleven separate tables to permit similar objects to be listed together. An additional 426 stars whose spectra show bright lihes of ionized calcium are also included. The bibliography gives references to all spectroscopic observations of the stars having bright hydrogen lines, but only references pertaining specifically to observations of the emission lines in the case of the Ca U emission stars. In all, 903 references are listed: An extensive set of remarks accompanies the catalogue, giving supplementary or previously unpublished data concerning the objects included.
