We present the results of a search for cool subdwarfs for which ourcandidates were drawn from a V-J reduced proper-motion diagram constructed bySalim & Gould (2002). Kinematic (U, V, and W) and self-consistent stellarparameters (Teff, log g, [Fe/H], and V_t) are derived for 91 candidatesubdwarfs based on high resolution spectra. The observed stars span 3900K
