Description (Abstract of paper):
    Positions, redshifts, and magnitudes for the 1055 quasars in the Large
    Bright Quasar Survey (LBQS) are presented in a single catalog.
    Celestial positions have been rederived using the PPM catalog to
    provide an improved reference frame. J2000.0 coordinates are given
    together with improved B1950.0 positions. Redshifts calculated via
    cross correlation with a high signal-to-noise ratio composite quasar
    spectrum are included and the small number of typographic and redshift
    misidentifications in the discovery papers are corrected.

    Compared to the discovery papers (references below), quasars fainter
    than the limit have been deleted, 12 quasars have been added, 10
    redshifts have been corrected, and 13 designations (LBQS names) have
    been corrected.
