  Libraries of stellar spectra are fundamental tools for the study of stellar
populations and both empirical and synthetic libraries have been used for this
purpose. In this paper, a new library of high resolution synthetic spectra is
presented, ranging from the near-ultraviolet (300nm) to the near-infrared
(1.8${\rm \mu}$m). The library spans all the stellar types that are relevant to
the integrated light of old and intermediate-age stellar populations in the
involved spectral region (spectral types F through M and all luminosity
classes). The grid was computed for metallicities ranging from [Fe/H] = --2.5
to +0.5, including both solar and $\alpha$-enhanced ([$\alpha$/Fe] = 0.4)
chemical compositions. The synthetic spectra are a good match to observations
of stars throughout the stellar parameter space encompassed by the library and
over the whole spectral region covered by the computations.
