cds-question@unistra.frvisible-astronomytrigonometric-parallaxinfrared-photometrybroad-band-photometryContinuing our census of late-type dwarfs in the solar neighborhood, we present BVRI photometry and optical spectroscopy of 800 mid-type M dwarfs drawn from the NLTT proper-motion catalog. The targets are taken both from our own cross-referencing of the NLTT Catalogue and the 2MASS Second Incremental Data Release, and from the revised NLTT compiled recently by Salim & Gould (Cat. <J/ApJ/582/1011>). All are identified as nearby-star candidates based on their location in the (m_r_, m_r_-K_s_) diagram. Three hundred stars discussed here have previous astrometric, photometric, or spectroscopic observations. We present new BVRI photometry for 101 stars, together with low-resolution spectroscopy of a further 400 dwarfs.2004AJ....128..463Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/463CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/98 : NLTT Catalogue (Luyten,
