Boss General Catalogue (GC)
The General Catalogue of 33,342 Stars, compiled by the American astronomer Benjamin Boss (1880-1970) and published by the Carnegie Institution of Washington, DC, in 1936. It lists the position, proper motion, magnitude, and spectral type of all stars brighter than seventh magnitude over the whole sky, plus some fainter stars for which accurate proper motions were available. It succeeded the Preliminary General Catalogue of 6,188 stars, published by Benjamin's father, Lewis Boss (1846-1912), who also initiated the larger work.
