The observational program “Deep spectral survey of the selected sky areas” on the 6-meter telescope is described. Preliminary results for the central part of field SA57 are discussed. The spectrum of a QS0 with probable redshift z=3.87 is presented. The number of quasars per sq. degree is estimated to be 470–675 to B < 23 mag., which gives the same slope in the increasing number of QSOs with magnitude as in brighter samples.
