We present a further list of 274 bright QSOs, 106 (195) of which have $B\mathrel{\mathchoice {\vcenter{\offinterlineskip\halign{\hfil
$\displaystyle ... (17.5), selected semiautomatically from objective prism plates taken with the Calar Alto 80cm Schmidt telescope. All QSOs have been confirmed by follow-up spectroscopy and we display their flux-calibrated spectra. We also discuss the completeness of our search technique and demonstrate that for $0.1 \le z < 3.2$ and $B \le 17$ we have been able to recover roughly 85% of known QSOs; 10% were lost due to overlaps while 5% were lost during the selection process. In particular the bright $z \ge 2$ QSOs (17 with $B\mathrel{\mathchoice {\vcenter{\offinterlineskip\halign{\hfil
$\displaystyle ... ) are potential targets for follow-up spectroscopy both at high-resolution from the ground and in the ultraviolet from space.
