The Hamburg Quasar Survey (Hagen et al. 1995; hereafter Paper I) covers 13600 deg2 of the northern sky () at galactic latitudes with digitized objective prism plates. Given effective and robust search techniques the digitized database of objective prism spectra is well-suited to make searches for objects with low surface densities in the sky. The search technique currently used to select bright (17.5) QSO candidates from the database has developed with growing experience. We present here a first list of 121 spectroscopically verified QSOs observed during 1986-1991, while experiments were made to optimize the selection technique over a wide range of optical brightnesses (1319.5) corresponding to the full dynamical range of the Schmidt objective prism plates. For details on the Schmidt observations and the digitization method we refer to Paper I.
