We present the XMM-Newton sample in the Chandra/SWIRE field. We compare the recent XMM (2008-2009) and previous Chandra (2004) observations to identify a sub-sample of variable sources. We find that variability is independent of X-ray absorption and dust obscuration. The analysis of the radio fluxes reveals a significant fraction of radio-weak AGNs and a higher incidence of absorption among radio-loud sources. The source list and multi-wavelength catalogs in the Chandra/SWIRE field can be accessed through an on-line database.
