We present a catalog and first study of the Spectra Energy Distributions (SEDs) as a function of luminosity and redshift of 278 X-ray (XMM) selected Type 1 AGNs from the wide-field "Cosmological Evolution Survey" (COSMOS), all of which have deep coverage and rich sampling of frequencies from X-ray to radio and spectroscopical confirmation from Magellan (IMACS), the MMT or the SDSS. We present the average SED and the dispersion SEDs before and after corrections of broad emission line photometry, Galactic extinction, and we limit our data to the interval of 2005 2007 to minimize variations. We then study the shape of the SEDs in redshift and bolometric luminosity bins, compared with the expected effects of host galaxy contamination and intrinsic extinction. These show that high redshift and high luminosity quasars depart from the mean SEDs of Elvis et al 1994.
