  Presented in this work is the most comprehensive INTEGRAL AGN sample: it
includes 272 active galaxies for which optical identifications and redshifts
are available. 2-10 keV fluxes and column density measurements are also
collected for all the sample sources. For 33 new hard X-ray discovered AGN with
no previous X-ray coverage, XRT and XMM data analysis is reported for the first
time in this work. Examples of future studies which are being developed using
this large X-ray selected sample are presented together with some early
results.
