The second part of the First Byurakan Survey is aimed at detecting all bright (B < 16.5) UV-excess starlike objects in a large area of the sky. By comparison with other major surveys such as the ROSAT All Sky Survey, the ROSAT WGACAT catalogue of point sources, the IRAS survey, the 6 cm Green Bank, the 1.4 GHz NRAO VLA and the 92 cm Westerbork Northern sky surveys and with the catalogue of mean UBV data on stars, the authors estimate the number of AGNs present in the FBS survey and its completeness. The authors have made spectroscopic observations on nine of the most promising FBS candidates. They have found six new QSOs bringing the total number of known QSOs in this survey to 42. By comparison with the Bright Quasar Survey, they found that the completeness of this last survey is of the order of 70% rather than 30 - 50% as suggested by several authors.
