Our sample of spectroscopically confirmed AGN is primarily X-ray and radio selected and is especially sensitive to optically obscured AGN. We couple the multiwavelength spectral energy distribution of our Type 1 and Type 2 AGN along with measurements of their optical emission lines in order to study basic AGN physics. In particular, we estimate black hole masses and bolometric luminosities for ~100 Type 1 AGN. Our eventual goal is study of the coevolution of supermassive black holes and their environments with good statistics over most of cosmic time.
