The Transient Gamma-Ray Spectrometer (TGRS) on the WIND spacecraft is designed to perform spectroscopy of bright gamma-ray bursts (GRBs) in the {approx}20-8000 keV energy range, with a spectroscopic resolution which is 5-30 times better than that of earlier-generation detectors. During its first {approx}2.5 years of operation, TGRS detected {approx}90 GRBs, of which about one third are suitable for statistically interesting spectroscopy. We present preliminary comparative results for some of the brightest of those bursts, and which were also observed by CGRO/BATSE.
