				<para>
  The present catalogue presents a list of 3216 stars mostly earlier than type
  F which have shown emission features and specifically one or more lines of
  the Balmer series in emission. It is a compilation and rearrangement of the
  following lists: the Catalogue and Bibliography of Stars of Classes B and A
  whose spectra have bright H lines by P. Merrill and C. Burwell, the lists of
  Haro and his associates at Tonantzintla, the catalogues of Luminous Stars in
  the Northern Milky Way, Vols. I to VI published by the astronomers of the
  Hamburger Sternwarte and the Warner and Swasey Obs. Shorter lists of emission
  stars published by Parenago, Bidelman and McCarthy and Treanor have also been
  included. The present catalogue has a simple aim: to assist the astronomer in
  finding from a vast array of articles in the literature whether the star
  under investigation has been known to show emission features in the earlier
  major surveys of emission stars of early type carried out at the Mount
  Wilson, Tonantzila, Hamburg and Warner-Swasey Observatories. The catalogue
  includes the star identification, Durchmusterung identification, source
  catalog, RA and Dec, Galactic latitude and longitude, apparent magnitude,
  spectral classification and remarks.</para></description>

	<footnote>
			<para>
    The rubric that was adopted in the Henry Draper Catalogue of denoting
        declinations different from the declination of the 1900.0 epoch has
        been followed in the present catalogue. For example, Vatican No. 7
        which is the equivalent of Star No. 3 in the A catalogue (i.e.
        Merrill and Burwell: Mount Wilson Catalogue, Star No. 3) is indicated
        as BD -2829 to indicate, by reference to DE (60deg, 4arcmin), that
        this star is BD +59 2829. Thus, the "-" denotes in this catalogue
        (just as the italics did in the Henry Draper Catalogue) the fact of
        the change in declination of the star between the 1855 epoch of the
        Bonner Durchmusterung and the 1900 epoch adopted for all the stars
        in the present listing.</para></footnote></definition>

			<definition>Apparent Magnitude
	<footnote>
			<para>
    Apparent magnitudes as found in the original source catalogue.
    These are of necessity a mixture of visual magnitudes taken from various
        Durchmusterungs, photographic magnitudes interpolated from Selected
        Areas, open cluster sequences and in some cases derived directly
        by the various authors from visual inspection of spectrum plates.
        Hence very large differences in the published magnitudes for the
        same star are quite common even apart from the known or suspected
        variability of many of these stars.</para></footnote></definition>
