The SDSS produces flux densities in five bands to a depth of about\rm 23m with positional accuracy better than \rm 0.1''. We describe a general cross-correlation tool which matches up sources from other catalogues and those in the SDSS, and the use of this tool to match up SDSS and IRAS sources. We will compare the SDSS sources from test observations of the celestial equator at high galactic latitudes, taken in June - September 1998, with the IRAS Point Source and Faint Source Catalogues, and investigate the properties of stars with circumstellar dust and of cold IRAS sources. A goal of this investigation is to develop criteria for the identification of an IRAS source with its optical counterpart, and thereby to produce improved positions and source identifications for most of the high-latitude IRAS sources.
