        IRAS low-resolution spectra were extracted for 11,224 IRAS sources.
     These spectra were classified into astrophysical classes, based on the
     presence of emission and absorption features and on the shape of the
     continuum.  Counterparts of these IRAS sources in existing optical and
     infrared catalogs are identified, and their optical spectral types are
     listed if they are known.  The correlations between the photospheric/
     optical and circumstellar/infrared classifications are discussed.

     Subject headings: catalogs -- circumstellar matter -- infrared stars
                       -- stars: AGB and post-AGB --
                       stars: fundamental parameters
