  We present ELODIE.3.1, an updated release of the library published in
Prugniel & Soubiran (2001, 2004). The library includes 1962 spectra of 1388
stars obtained with the ELODIE spectrograph at the Observatoire de
Haute-Provence 193cm telescope in the wavelength range 390 to 680 nm. It
provides a wide coverage of atmospheric parameters : T_eff from 3100 K to 50000
K, log g from -0.25 to 4.9 and [Fe/H] from -3 to +1. The library is given at
two resolutions: R~42000, with the flux normalized to the pseudo-continuum,
FWHM=0.55\AA (R~10000) calibrated in physical flux (reduced above earth
atmosphere) with a broad-band photometric precision of 2.5% and narrow-band
precision of 0.5%.
  In this new release the data-reduction (flux calibration, reconnection of the
echelle orders) has been improved, and in particular the blue region, between
390 and 400 nm has been added.
  The FITS files for each spectra, and the measured atmospheric parameters are
publicly available.
