cds-question@unistra.frgalaxiescatalogssurveysh-i-line-emissionNeutral hydrogen observations at 21cm, made at the Green Bank 91m telescope in 1984, 1985 and 1986, of a large sample of dwarf and other low surface brightness galaxies are presented. The majority of galaxies classified in the Uppsala General Catalogue as dwarf, irregular, Sdm, or later and with declinations north of the range of the Arecibo telescope ({delta}>38{deg}) have been observed, along with a number of galaxies farther south for flux comparisons with Arecibo observations (Schneider et al., 1990ApJS...72..245S, Paper I), totaling over 600 galaxies. About half of these galaxies have no previously published detections. In total, counting previous detections, over 80% of these late-type systems are detected at Green Bank. We have examined the galaxies for potential confusion with nearby galaxies, and we also present substantially better signal-to-noise measurements for many previously detected galaxies. Some general results of the Green Bank survey are discussed here, but the total data base of northern dwarf and low surface brightness galaxies, including new measurements of the galaxies' photographic magnitudes, will be examined in subsequent papers.1992ApJS...81....5Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/81/5CatalogResearchIsServedByTAP VizieR generic
