We present a new theoretical library of stellar spectra covering the wavelength interval from 850 to 7000 Å. The library consists of two datasets, one including the far UV-blue spectral region from 850 to 4750 Å at inverse spectral resolution R = 50000, and the latter spanning the range 3500-7000 Å at R = 500000. Both sets are based on the SYNTHE series of codes developed by R.L. Kurucz. For its comprehensive range of physical parameters (i.e. T[eff], logg and [M/H]) and higher spectral resolution, this is the most advanced spectral library currently available in the literature, and could profitably be used for population synthesis models and abundance studies of single stars.
