Seven low redshift QSOs have been observed spectroscopically at infrared and optical wavelengths at McDonald Observatory. The two instruments used were the infrared grating spectrometer (IRGS; see Lester, Harvey, and Carr 1988 for a description) on the 2.7m reflector, and the es-2 cassegrain spectrometer on the 2.1m. Table 1 shows the objects and spectra taken.
