J/MNRAS/260/202 J/MNRAS/260/202 Quasar luminosity function M R S Hawkins P Veron Mon. Not. R. Astron. Soc. 260 202 1993 1993MNRAS.260..202H cosmology: observations quasars: general A sample of quasars is selected from a 10-yr sequence of 30 UK Schmidt plates. Luminosity functions are derived in several redshift intervals, which in each case show a featureless power-law rise towards low luminosities. There is no sigh of the 'break' found in the recent UVX sample of Boyle, Shanks & Peterson. It is suggested that reasons for the disagreement are connected with biases in the selection of the UVX sample. The question of the nature of quasar evolution appears to be still unresolved.
