We have used the Very Large Array(VLA) in C configuration to carry out a sensiti ve 20cm radio survey of regions of sky that have been surveyed in the Far InfraR ed over the wavelength range 5-200 microns with ISO as part of the European Larg e Area ISO Survey(ELAIS). As usual in surveys based on a relatively small number of overlapping VLA pointings the flux limit varies over the area surveyed. The survey has a flux limit that varies from a 5oe limit of 0.135mJy over an area of 0.12deg2 to a 5oe limit of 1.15mJy or better over the whole region covered of 4 .22 deg2. In this paper we present the radio catalogue of 867 sources. These reg ions of sky have previously been surveyed to shallow flux limits at 20cm with th e VLA as part of the VLA D configuration NVSS(FWHM=45 arcsec) and VLA B configur ation FIRST(FWHM=5 arcsec) surveys. Our whole survey has a nominal 5 sigma flux limit a factor of 2 below that of the NVSS; 3.4 deg2 of the survey reaches the n ominal flux limit of the FIRST survey and 1.5 deg2 reaches to 0.25 mJy, a factor of 3 below the nominal FIRST survey limit. In addition our survey is at resolut ion intermediate between the two surveys and thus is well suited for a compariso n of the reliability and resolution dependent surface brightness effects that af fect interferometric radio surveys. We have carried out a a detailed comparison of the reliability of our own survey and these two independent surveys in order to assess the reliability and completeness of each survey.
