The solar neighborhood. 2: The first list of dwarfs with spectral types of M7 and cooler

Spectra and finder charts are given for 20 dwarfs having types of M7 or later, and a spectral classification scheme is introduced for types M7 V to M9 V. Three of these dwarfs are later that M9 and have spectra in which VO absorption appears greatly enhanced. First results are also presented for a spectroscopic follow-up of unclassified proper motion targets, begun in an attempt to identify other low-luminosity members of the solar neighborhood.
