We present a database of 908 spectra of 709 stars obtained with the ELODIE spectrograph at the Observatoire de Haute-Provence. 52 orders of the echelle spectra have been carefully tted together to provide continuous, high-resolution spectra in the wavelength range = 410 680 nm. The archive provides a large coverage of the space of atmospheric parameters: Te from 3700 K to 13 600 K, log g from 0.03 to 5.86 and (Fe/H) from 2:8 to +0.7. At the nominal resolution, R = 42 000, the mean signal-to-noise ratio is 150 per pixel. The spectra given at this resolution are normalized to their pseudo-continuum and are intended to serve for abundance studies, spectral classication and tests of stellar atmosphere models. A lower resolution version of the archive, at R = 10 000, is calibrated in physical flux with a broad-band photometric precision of 2.5% and narrow-band precision of 0.5%. It is well suited to stellar population synthesis of galaxies and clusters, and to kinematical investigations of stellar systems. The archive is distributed in FITS format through the HYPERCAT and CDS databases.
