Mining The Local Universe for Data: the QSO Luminosity Function with the Asiago-ESO/RASS QSO Survey

We present progress results of a new survey for bright QSOs (V<14.5, R<15.4, B_J<15.2) covering the whole sky at |b|>30. The surface density of QSOs brighter than B_J=14.8 turns out to be $2.9\pm 0.8\cdot {10}^{-3}de{g}^{-2}$. 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.
