The Burst Alert Telescope (BAT) on board the Swift satellite has accumulated light curves for approximately 200 sources in the energy range 14 to 200 keV. These light curves now have an extent of approximately one year and have time resolutions of 5 minutes or better. We present here an analysis of the strongest sources (> 100) in four energy bands and search for periodicities on timescales that correspond to orbital and super-orbital periods in X-ray binaries. We compare our results to those obtained at lower energies such as from observations with the RXTE All-Sky Monitor.
