A far-UV (lambda lambda 1230 to 1900A) stellar library was extended to the mid-UV wavelength range (lambda lambda 1900 to 3200A) using low resolution spectra obtained from the IUE Spectral Atlas and new cool (FGK) star spectra. A set of spectral energy distributions of common stellar types ranging from O3 to M0 is derived for this entire wavelength range. The usefulness of various spectral diagnostics in the mid-UV such as Mg I lambda 2852A, Mg II lambda 2798A, and the Fe II blend near lambda 2400 was examined. The library extends the analysis of the stellar populations in actively star-forming galaxies to cooler (A-F) spectral types, thereby probing the intermediate age (1-5 Gyr) stellar content in these galaxies. The library is also useful for synthesis of the mid-UV spectra of old stellar populations.
