The Transient Gamma-Ray Spectrometer (TGRS) is a germanium spectrometer designed to produce high-resolution (2-3 keV) spectra of bright gamma-ray bursts. In its first year of operation it has triggered on 62 GRBs, of which {approx}33 were bright enough for spectroscopy. Almost all of these bursts were also seen by the Konus detectors on the same spacecraft, and about half were also observed by BATSE. This allows the instruments and their results to be compared and will allow line candidates seen by any of the instruments to be confirmed or refuted by the others. This paper presents some typical spectra from GRBs observed by TGRS, and includes for comparison the corresponding BATSE and Konus spectra.
