Abstract:
    An atlas on microfiche is described containing nearly 7000 high-dispersion
    spectra of OB stars obtained during the first 10 years with the IUE
    satellite. The data set is nearly complete for the selected time interval.
    The plotted wavelength range is from 1160 to 1890 A at the original IUE
    sampling intervals.
