Abstract: New results on the clustering and evolution of QSOs at z less than 2.9 were derived using two recently completed surveys for faint QSOs. Strong luminosity evolution was observed at low redshifts but 'switched off' at z = 2 with the comoving space density of QSOs remaining constant in the redshift range 2 to 2.9. Extrapolation of this evolution to higher redshifts implies little decrease in the comoving space density of bright QSOs at z less than 4.5. Strong QSO clustering was observed at small separations but no significant evidence was found for evolution in the strength of QSO clustering with cosmic epoch.
