Spectroscopy and spectral types for 387 stellar objects brighter than BJ = 18.75 found in the Large, Bright QSO Survey (LBQS) are reported. The spectra were observed with the MMT at moderate resolution (6 A FWHM) and low S/N, and cover the wavelength interval 3200-7400. They represent all of the northern hemisphere Galactic LBQS objects observed through 1989 September. The identification and spectra of one DQA, 10 DB, two DC, three DQ, and three DZ white dwarfs are presented, as well as seven composite objects and five cataclysmic variables and unredshifted emission objects. Additionally, the identification of 103 hot subdwarfs and horizontal-branch stars, 224 late-type stars, an additional composite object, and 28 DA white dwarfs is reported. Equivalent width measurements for the white dwarf stars, and descriptions of the more peculiar objects, are included.
