Abstract
We present progress results of a new survey for bright QSOs (V<14.5, R<15.4, BJ<15.2) covering the whole sky at high galactic latitudes, |b|>30. The surface density of QSOs brighter than BJ=14.8 turns out to be 2.9 +- 0.8 10-3 deg-2. The optical Luminosity Function at 0.04 < z < 0.3 shows significant departures from the standard pure luminosity evolution, providing new insights in the modelling of the QSO phenomenon.
