We calculate and present the quasar luminosity function (QLF) using data from 30,000 new, z>2 quasars from the SDSS-III: Baryon Oscillation Spectroscopic Survey (BOSS). The BOSS data, along with the original SDSS-I/II, and the 2SLAQ QSO survey, will help cover luminosity-redshift (L-z) plane, such that there is a 4 magnitude dynamic range from redshifts z=0-4. In particular, the g=22.0 BOSS quasars fill in the z=2.2-3.5 redshift range, key for investigations for the faint-end of the QLF at the height of the ``quasar epoch''. We use our new measurements to map the black hole accretion history of the Universe and constrain how quasars contribute to the ``AGN feedback'' cycle in galaxy formation.
