Recent results at high redshifts are briefly reviewed. An analysis of the evolution of the quasar luminosity function based on the recently published Hawkins & Véron (1995) variability-selected quasar sample is presented. The results support the conclusions of earlier work that suggested the simple two power law luminosity function, of invariant shape as a function of redshift, requires some modification in order to match the data. However, the contention of Hawkins & Véron that a single power law model provides an adequate fit to the variability-selected quasar sample and that there is no requirement for curvature in the form of the quasar luminosity function is not borne out by the analysis.
