The IRTS data archive has been in public since 2002. IRTS surveyed about 7 per cent of the whole sky with four instruments, which covered from 1.4 to 700 μm. Presently the archive includes the near- and mid-infrared low resolution spectral catalogues of point sources, and image maps in five wavelength bands in the far-infrared. The point source catalogues contains over 14 000 (near-infrared) and 500 (mid-infrared) sources. The majority of detected sources are late-type stars. These large samples of uniform spectra are especially useful for statistical studies of infrared properties of stars. The far infrared image maps are obtained for the 158 μm [C II] line, and continuum bands at 155, 250, 400, and 700 μm. Radiation from the diffuse interstellar components has been studied with these data. More data products will be available in a few year time-scale. The IRTS data can be accessed via ISAS's data archive service DARTS, URL:
