We assemble optical/infrared spectral energy distributions (SEDs) for 45 X-ray/24µm sources in the EGS and LH. Only about one-quarter of the hard X-ray/24µm sources show pure type 1 active galactic nucleus (AGN) SEDs. More than half of the X-ray/24µm sources have stellar emission-dominated or obscured SEDs, similar to those of local type 2 AGN and spiral/starburst galaxies. One-third of the sources detected in hard X-rays do not have a 24µm counterpart. Two such sources in the LH have SEDs resembling those of S0/elliptical galaxies. The broad variety of SEDs in the optical-to-Spitzer bands of X-ray-selected AGNs means that AGNs selected according to the behavior in the optical/infrared will have to be supplemented by other kinds of data (e.g., X-ray) to produce unbiased samples of AGNs.
