## Abstract Extensive programs of followβup observations of hard Xβray selected sources have unambiguously revealed that the sources of the Xβray background are characterized by an extremely large dispersion in their optical magnitude and spectroscopic classification. Here we present the results of

Seyfert galaxies were classified on the basis of their optical spectroscopic properties into types 1 and 2, (Weedman 1970, Weedman 1973 and Khachikian & Weedman 1974). This enduring classification highlighted an important physical distinction and ultimately led to Unified Schemes for AGN, which have
