The aim of this paper is to provide an unbiased and quantitative description of the X-ray source population at these fluxes and in various X-ray energy bands. We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comprises four largely overlapping source samples selected at soft (0.5-2keV), intermediate (0.5-4.5keV), hard (2-10keV) and ultra-hard (4.5-7.5keV) bands, the first three of them being flux-limited.
