Popular name for the five-volume General Catalogue of 33,342 Stars compiled in 1936–7 by the American astronomer Benjamin Boss (1880–1970). This catalogue contains positions and proper motions of all stars brighter than 7th magnitude over the whole sky, plus thousands of fainter stars for which accurate proper motions could be determined. It was a successor to the Preliminary General Catalogue of 6188 stars published in 1910 by his father, Lewis Boss (1846–1912), who also initiated the larger catalogue.
