dc.descriptionUpdates are provided on several issues related to Unified Models. A new HST spectrum of Cygnus A confirms the broad MgII emission line, and suggests a very large velocity width as seen in the polarized optical lines. Statistics of the 3CR sample are discussed, with emphasis on the role of mid-IR data to distinguish hidden quasars from "nonthermal AGN". A nearly diffraction-limited 10-micron Keck image of 3C390.3 reveals two point sources. A program of Keck longslit spectropolarimetry of distant radio galaxies, radio emitting BALs, and a red quasar is summarized. Most observations can be accounted for by the Unified Model, but the aligned radio galaxy 4C41.17 at Z=3.8 shows only unpolarized starlight. Finally far-IR, submillimeter, and molecular work on distant radio quiet quasars is described, including some details from the high resolution mapping of the Cloverleaf quad lens.
