The Next Generation Spectral Library is an HST snapshot program using STIS to produce a UV/optical stellar spectral atlas for modeling the integrated light of composite systems. This program has been using the low dispersion gratings and CCD detector of STIS to take high S/N spectra of targets roughly equally divided among four metallicity groups: very low ([Fe/H] < -1.5), low (-1.5 < [Fe/H] < -0.5), near-solar (-0.3 < [Fe/H] < 0.1), and super-solar ([Fe/H] > 0.2), well-sampling the entire HR-diagram in each bin. The failure of STIS in August 2004 has ended data acquisition at 380 stars, short of the goal of 600; even so, the NGSL surpasses all extant compilations in terms of metallicity and wavelength coverage. The spectra, once properly calibrated, will be made publicly available via our website and others. We acknowledge support from NASA through grants from STScI (9088 & 9786). Much of this work was done at the Institute of Geophysics and Planetary Physics, under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under contract No.\ W-7405-Eng-48.
