Abstract
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 fitted together to provide
continuous, high-resolution spectra in the
wavelength range 
nm. The archive provides a large coverage of the
space of atmospheric parameters:
Teff from 3700 K to 13 600 K, 
from 0.03 to 5.86
and [Fe/H] from -2.8 to +0.7.
At the nominal resolution, 
, 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
classification and tests of stellar atmosphere models.
A lower resolution version of the archive, at 
, 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.
Key words: atlases / stars: abundances / stars: atmospheres / stars: fundamental parameters / galaxy: stellar content
Based on observations made on the 193 cm telescope at the Haute-Provence Observatory, France.
