In AGN in the year 2000. Fourth National Meeting on Active Galactic Nuclei, Trieste, 15 - 18 May 2000, edited by A. CelottiThe results of a 2 - 10 keV BeppoSAX X-ray survey based on 140 high galactic latitude MECS fields are presented. About 25% of the Cosmic X-ray Background (CXB) is resolved into discrete sources at the sensitivity limit of the survey (S ~ 510<SUP>-14</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP>). The log N-log S relationship, built with the 177 X-ray sources of the survey, is steep and in good agreement with that derived from ASCA surveys. The results of a CXB fluctuation analysis, which probes the log N-log S down to about 110<SUP>-14</SUP> erg cm<SUP>-2</SUP> s<SUP>-1</SUP>, are also presented.http://adsabs.harvard.edu/abs/2001MmSAI..72..203P2001MmSAI..72..203P
