The Infrared Space Observatory (ISO) took almost 1250 2.4-45.2 μm spectra of over 900 celestial objects with the Short Wavelength Spectrometer in full-grating mode. Based on these data, we have developed a comprehensive system of infrared spectral classification. The primary discriminant between the classes is the temperature of the dominant emitter, e.g. a hot stellar photosphere or a cold dust cloud. Subgroups are made up of objects with similar spectral features, such as silicate absorption or atomic fine-structure lines. We have also created an atlas of uniformly processed spectra from these data. Starting from the most processed form available from the ISO Data Archive, which consists of 288 spectral segments per observation, we have reduced and combined these data into single, continuous spectra. The classifications, atlas, and processing software have been submitted for publication in the Astrophysical Journal Supplement and will also be available to the general astronomical community upon request.
