  We present preliminary results on the XMM-Newton Survey Science Centre medium
sensitivity survey (XMS), with 0.5-4.5 keV flux limit 2 10^{-14} erg/cm2/s. At
present, 19 fields have been examined with a total of 239 X-ray sources.
Identifications for about 2/3 of these reveal that type 1 AGN dominate, but
type 2 AGN, absorption-line galaxies and clusters as well as stars are also
present. We also discuss on a few X-ray selected Broad-Absorption-Line QSOs
found in this survey.
