Neutral hydrogen observations of a large sample of dwarf and other low surface brightness galaxies are presented. Nearly all galaxies classified in the Uppsala General Catalogue as dwarf, irregular, Sd-m, or later and in the declination range of the Arecibo telescope have now been observed; here observations for 762 galaxies are reported. About 40 percent of these galaxies have no previously published detections. In total, counting previous detections, over 90 percent of these late-type systems are detected at Arecibo. The galaxies are examined for potential confusion with nearby galaxies, and substantially better SNR are derived for many previously detected galaxies.
