The GMRT has been used to make deep, wide-field surveys of several fields at 610 MHz, with a resolution of about 5~arcsec. These include the Spitzer Extragalactic First Look Survey field, where 4 square degrees were observed with a r.m.s. sensitivity of about 30~μ Jy~beam-1, and several SWIRE fields (namely the Lockman Hole, ELAIS-N1 and N2 fields) covering more than 20 square degrees with a sensitivity of about 80~μJy~beam-1 or better. The analysis of these observations, and some of the science results are described.
