We present a multi-wavelength catalog of radio objects created by positionally matching the FIRST, NVSS, WENSS, GB6, and SDSS photometric and spectroscopic surveys. The complete catalog contains over 2 million objects detected by at least FIRST or NVSS with over 400,000 detected by both, and about 20,000 detected by all four radio surveys. We examine the distribution of optically classified galaxies and quasars in radio color-color, magnitude, and morphology space to investigate the radio galaxy/quasar unification paradigm. Further applications include statistical analysis of the impact of radio sources on their environment as a function of morphology, examination of the accuracy radio galaxy evolution models, and detailed studies of the properties of quasars with jets or lobes. This catalog will also be a significant source of certain rare objects such as radio stars and very high-redshift quasars.
