The range of continuum shape the quasar phenomenon covers is larger than is usually thought, and is limited by observational sensitivity, between 1/3 and 1/2 of all quasars are “extreme” in at least one band. We have embarked on a program of observations to explore extreme spectral shapes, and to push to high redshift/luminosity. This paper presents X-ray and multi-wavelength SEDs for 12 z∼3 quasars.
