Abstract
We present a further list of 274 bright QSOs, 106 (195) of which have
B <= 17 (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 < z < 3.2 and B <= 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 >= 2 QSOs (17 with B <= 17)
are potential
targets for follow-up spectroscopy both at high-resolution from
the ground and in the ultraviolet from space.
