Interstellar C IV absorption-line studies of the hot gaseous halo of the Large Magellanic Cloud (LMC) have been hindered by nonideal selections of early-type probe stars in regions where C+3 can be produced locally via photoionization, fast stellar winds, or supernovae. To observe stars outside such regions, precise spectral classifications of OB stars in the field are needed. Therefore, we have obtained medium-dispersion spectra of 42 early-type stars in the LMC that are distributed outside superbubbles or supergiant shells. The spectral classification of these stars is presented in this paper. Nineteen of these program stars have spectral types between B1 and O7 and are thus suitable probes for interstellar C IV absorption-line studies of the hot gaseous halo of the LMC.
