Abstract • A spectroscopic survey of a large sample of luminous infrared galaxies [log (L_ir_/L_sun_)^7^ ~ 10.5-12.5; H_0_ = 75 km s^-1^ Mpc^-1^] has been carried out using the Palomar 5 m telescope,, and the University of Hawaii 2.2 m telescope. Long-slit spectra covering 375o-8000 A at a resolution of ~10 A were obtained of 200 IRAS galaxies, including 114 objects from the IRAS Bright Galaxy Survey, and 86 objects with fainter infrared fluxes selected on the basis of their "warm" far-infrared (S_60_/S_100_) colors. The methods of observation and data reduction are discussed. An atlas of the spectra extracted from the nuclear region of these objects is presented along with a large number of parameters describing the properties of the emission lines, the stellar absorption lines, and the continuum emission that were measured from the spectra. An analysis of these data is presented in a companion paper (Veilleux et al. 1995) along with a discussion of the spatial variations of these parameters in a subsample of twenty-three objects.
