  We present a catalog of hard X-ray sources detected in the first 105 months
of observations with the Burst Alert Telescope (BAT) coded mask imager on board
the Swift observatory. The 105 month Swift-BAT survey is a uniform hard X-ray
all-sky survey with a sensitivity of $8.40\times 10^{-12}\ {\rm erg\ s^{-1}\
cm^{-2}}$ over 90% of the sky and $7.24\times 10^{-12}\ {\rm erg\ s^{-1}\
cm^{-2}}$ over 50% of the sky in the 14-195 keV band. The Swift-BAT 105 month
catalog provides 1632 (422 new detections) hard X-ray sources in the 14-195 keV
band above the 4.8{\sigma} significance level. Adding to the previously known
hard X-ray sources, 34% (144/422) of the new detections are identified as
Seyfert AGN in nearby galaxies (z<0.2). The majority of the remaining
identified sources are X-ray binaries (7%, 31) and blazars/BL Lac objects (10%,
43). As part of this new edition of the Swift-BAT catalog, we release
eight-channel spectra and monthly sampled light curves for each object in the
online journal and at the Swift-BAT 105 month Web site.
