The Swift/BAT team announces a new website featuring 153 AGN found in the first 9 months of the BAT all sky survey. Several of the detections in the 9-month survey are the first high energy detections of these galaxies, including objects not known to be AGN before detection in this survey. The website can be found at http://swift.gsfc.nasa.gov/docs/swift/results/bs9mon/. The website presents the data from the BAT instrument for the catalog sources including the hard X-ray flux in 4 bands and the 9-month lightcurves. The BAT survey is fairly uniform across the entire sky; the 4.8 sigma threshold in the 9-month survey covers 80% of the sky at a flux threshold of 3.5x10-11 ergs/cm2/s in the 14-195 keV band and covers one third of the sky near the ecliptic poles to 2.5x10-11 ergs/cm2/s. A full description of the survey and the 9-month AGN catalog can be found in Tueller et al. (arXiv:0711.4130). The full BAT data set is archived at the HEASARC and available to the public.
