  We present preliminary results of a large project aimed at creating an
extended theoretical and observational database of stellar spectra in the
ultraviolet wavelength range. This library will consist of IUE spectra at low
and high resolution, and a set of LTE and NLTE theoretical fluxes. A first grid
of 50 model fluxes with solar metallicity, in the wavelength interval 1000 -
4400 AA, is reported here. Calculations are based on the Kurucz (1993) SYNTHE
code. The models span effective temperatures between 10,000 K and 50,000 K, and
a surface gravity in the range 2.5 <= log g <= 5.0 dex.
