The NEWSIPS-reprocessing of IUE data permits the extraction of spectra to wavelengths as short as 1150 Å. We present representative well-exposed IUE spectra of Wolf-Rayet stars covering the 1150–1220 Å region with a resolution of 0.1 Å. The C III 1175 Å line in WC and some WN stars typically shows a P-Cygni profile, with dacs apparent in time series spectra. Superimposed on the stellar spectra are many strong interstellar absorption lines of N I, Si II and other species. These spectra are a guide to a portion of the wavelength region to be covered by FUSE, and an indication of the new information that will be available in the far-UV range with FUSE.
