We present results from the first 22 months of the Swift/BAT hard X-ray survey. The BAT hard X-ray (15-200 keV) instrument has been collecting data for three years and has produced the deepest all-sky map of the hard X-ray sky yet produced. The 22 month data contain over 500 sources detected at the 4.8 sigma level, of which approximately 300 are AGN. This corresponds to fluxes as low as 1.8e-11 ergs/cm2/sec.
We present the list of detected AGN, galaxy clusters, and galactic objects by class as well as show a remarkably clean correlation of hard X-ray flux to far IR flux for the AGN in the BAT catalog which indicates that the hard X-ray band is the most unbiased waveband for selecting AGN.
