Computing the basic accretion parameters for the supermassive black holes expected to be present in quasars is still a major challenge. In this paper we stress how a systematization of observational properties through the so‐called “eigenvector 1” of quasars helps to develop a clearer view of the structure and dynamics of the Broad Line Region ...
