The International Gamma-Ray Astrophysics Laboratory (INTEGRAL), launched in2002, continues its successful work in observing the sky at energies E>20 keV.The legacy of the mission already includes a large number of discovered orpreviously poorly studied hard X-ray sources. The growing INTEGRAL archiveallows one to conduct an all-sky survey including a number of deepextragalactic fields and the deepest ever hard X-ray survey of the Galaxy.Taking advantage of the data gathered over 17 years with the IBIS coded-masktelescope of INTEGRAL, we conducted survey of hard X-ray sources, providingflux information from 17 to 290 keV. The catalog includes 929 objects, 890 ofwhich exceed a detection threshold of 4.5 sigma and the rest are detected at4.0-4.5 sigma and belong to known cataloged hard X-ray sources. Among theidentified sources of known or suspected nature, 376 are associated with theGalaxy and Magellanic clouds, including 145 low-mass and 115 high-mass X-raybinaries, 79 cataclysmic variables, and 37 of other types; and 440 areextragalactic, including 429 active galactic nuclei (AGNs), 2 ultra-luminoussources, one supernova (AT2018cow) and 8 galaxy clusters. 113 sources remainunclassified. 46 objects are detected in the hard X-ray band for the firsttime. The LogN-LogS distribution of 356 non-blazar AGNs is measured down to aflux of 2E-12 erg/s/cm2 and can be described by a power law with a slope of1.44 +/- 0.09 and normalization 8E-3/deg2 at 1E-11 erg/s/cm2. The LogN-LogSdistribution of unclassified sources indicates that the majority of them are ofextragalactic origin.
