The Hamburg Quasar Survey is a wide-angle objective prism survey
for finding bright QSOs in the northern extragalactic sky
|b| > 20 deg; delta > 0 deg). The taking of the
prism plates for 567 fields covering this area was completed in 1997.
Including direct plates
for fields with delta > 20 deg the plate archive contains now 1871 plates.
In this paper we
present a first list of 121 quasars,
which were verified by slit
spectroscopy in the years 1986-1991, while experiments to develop
efficient selection techniques were made. The sample contains
objects with brightnesses 15 <= B <= 19.5 and redshifts
z <= 2.8 collected over various parts of the sky,
for which objective prism plates were available at that time.
