We present an atlas of near-infrared spectra (2.36{mu}m-4.1{mu}m) of ~300 stars at moderate resolution ({lambda}/{delta}{lambda}~1500-2000). The spectra were recorded using the Short-Wavelength Spectrometer aboard the Infrared Space Observatory (ISO-SWS). The bulk of the observations were performed during a dedicated observation campaign after the liquid helium depletion of the ISO satellite, the so-called post-helium programme. This programme was aimed at extending the MK-classification to the near-infrared.
