Since the publication of the MKK atlas in 1943, there has been much progress in (1) the construction of fast spectrographs of higher resolution, C2) faster fine-grain emulsions and sensitizing techniques, (3) the partial or complete explanations of certain spectroscopic effects, [4) the discovery of other spectroscopic effects, and C5) refinements in the classification system based on new spectra and data on luminosities. An interim atlas entitled An Atlas of Low-Dispersion Grating Stellar Spectra was published in 1968 by Abt, Meinel, Morgan, and Tapscott but it is out of print and was not reissued in anticipation of the forthcoming greatly-improved atlas.
