The radio counterparts to the IRAS Redshift Survey galaxies are identified in the NRAO VLA Sky Survey (NVSS) catalog. Our new catalog of the infrared flux-limited (S60 >= 2 Jy) complete sample of 1809 galaxies lists accurate radio positions, redshifts, and 1. 4 GHz radio and IRAS fluxes. This sample is six times larger in size and five times deeper in redshift coverage (to z ~ 0. 15) compared with those used in earlier studies of the radio and far-infrared (FIR) properties of galaxies in the local volume. The well known radio-FIR correlation is obeyed by the overwhelming majority (>98%) of the infrared-selected galaxies, and the radio AGNs identified by their excess radio emission constitute only about 1% of the sample, independent of the IR luminosity. These FIR-selected galaxies can account for the entire population of late-type field galaxies in the local volume, and their radio continuum may be used directly to infer the extinction-free star formation rate in most cases. Both the 1. 4 GHz radio and 60 micron infrared luminosity functions are reasonably well described by linear sums of two Schechter functions, one representing normal, late-type field galaxies and the second representing starbursts and other luminous infrared galaxies. The integrated FIR luminosity density for the local volume is 4. 8+/-0. 5 x 10⁷ L (sun) per Mpc³, less than 10% of which is contributed by the luminous infrared galaxies with L (FIR) > 10^11 L (sun). The inferred extinction-free star formation density for the local volume is 0. 015 +/- 0. 005 solar mass per year per Mpc³.
