14th General Catalogue of MK Spectral Classification

It is based on an extensive search of the literature published from ~1997 to 1999. Each catalog is essentially self-contained, with its separate selection of stars listed in order of increasing right ascension.

Some classifications (indicated between parentheses) are inferred from photometric or astrometric considerations. The preferred identification is from the Henry Draper Catalog or the General Catalog of Variable Stars, with a Durchmusterung or other alternative as space permits.
