Recent Sloan Digital Sky Survey data from observations of over 590 spectroscopic plates yield more than 20,000 spectroscopically confirmed QSOs with at least one emission line having FWHM > 1000 km/sec.

The quasar target selection algorithm (Richards et al., 2002) selects low-redshift quasars (z<3) and FIRST sources to i=19.1, as well as high-redshift quasars (z>3) to i=20.2. We apply the selection function in (redshift, magnitude) space to the QSO sample to determine the density and luminosity evolution of quasars.

We present the comoving space density, as a function of absolute magnitude and redshift.
