This white paper describes the science opportunities to greatly improve measurements of cosmological parameters from LSST which would be made possible by community access to deep (i 25), highly-multiplexed OIR multi-object spectroscopy (MOS) on 8-40m telescopes. Companion papers discuss opportunities from wide-field MOS and single-object data.
