Abstract

We report on an updated analysis of the cosmological evolution of optically selected QSOs incorporating, in addition to the data sets used in our previous work (Danese, De Zotti & Franceschini, 1985), the samples of Marshall et al. (1984), Koo (1983), Marano et al. (1984), Usher et al. (1983), Mitchell et al. (1984) and Weedman (1985).
