Large Bright Quasar Survey (LBQS) VII

In the 270 deg^2^ common to both surveys, the LBQS contains ~100,000 stellar and ~40,000 nonstellar objects, while the FIRST catalog contains ~25,000 sources. Cross-correlation of these lists yields 67 positional coincidences between known LBQS quasars and FIRST sources and an additional 19 stellar and 149 nonstellar positional coincidences with the radio catalog.

Spectroscopy of all the stellar matches and two-thirds of the nonstellar matches using the Keck I Telescope and the 6.5 m MMT produces eight new quasars. One BL Lac object, previously misclassified during the LBQS survey is also identified. The straightforward fractional incompleteness of the LBQS determined from this sample is 13%+/-4%, in good agreement with the published estimate of 10%.
