  We present the first results from the Australia Telescope Large Area Survey
(ATLAS), which consist of deep radio observations of a 3.7 square degree field
surrounding the Chandra Deep Field South, largely coincident with the infrared
Spitzer Wide-Area Extragalactic (SWIRE) Survey. We also list
cross-identifications to infrared and optical photometry data from SWIRE, and
ground-based optical spectroscopy. A total of 784 radio components are
identified, corresponding to 726 distinct radio sources, nearly all of which
are identified with SWIRE sources. Of the radio sources with measured
redshifts, most lie in the redshift range 0.5-2, and include both star-forming
galaxies and active galactic nuclei (AGN). We identify a rare population of
infrared-faint radio sources which are bright at radio wavelengths but are not
seen in the available optical, infrared, or X-ray data. Such rare classes of
sources can only be discovered in wide, deep surveys such as this.
