Even though the number of known quasars is approaching 2000, relatively few belong to well defined complete samples which are needed to derive their space distribution. For many years, the Braccesi survey (Braccesi, Formiggini, and Gandolfi 1970) was the only published one — its limited spectroscopic coverage allowed construction of only a small complete sample of 19 quasars brighter than B = 18, over an area of 36 sq. deg.
