Our objects are selected from the Spitzer Extragalactic First Look Survey and the SWIRE XMM-Newton Large-Scale Structure Survey (XMM-LSS) fields, with a typical 24um flux density of 5mJy. The median redshift is 0.6, with a range of ∼0.05-4. Only 33% (25 out of 77) of these objects are normal type 1 quasars, with no obscuration. Forty-four percent (34 out of 77) are type 2 objects, with high-ionization, narrow emission lines, and 14% (11 out of 77) are dust-reddened type 1 quasars, showing broad lines but a dust-reddened or unusually weak quasar continuum. Description: We selected samples of AGNs by mid-infrared color from the XFLS and SWIRE XMM-LSS fields. Most data were taken with the COSMIC instrument on the Palomar 200 inch (5m) telescope. Some spectra were obtained with the ISIS instrument at the 4.2m William Herschel Telescope (WHT) on La Palma, with the Echellette Spectrograph and Imager (ESI) at the Keck II telescope, or with the Kast spectrograph at the 3m Shane Telescope at Lick Observatory.
