A dedicated web site can be found here. The objective of this Stellar Library is to build an homogeneous library of stellar spectra in the visible range (3200 to 9500A), including stars of all spectral types, luminosity classes and metallicity that can be observed from the ground with the current instrumentation. Most of the stars in our sample have already well determined metallicities. The spectral resolution of our Stellar Library is about 3A FWHM.
