Abstract: We present a new spectral library, consisting in 3256 spectra covering 2043 stars. It combines high signal-to-noise and high spectral resolution over the entire range of effective temperatures and luminosity classes. The spectra are presented in four versions: raw, two 'Spectral Energy Distribution' (SED) versions, both corrected from the instrumental response, with and without correction for the molecular absorption of the Earth's atmosphere, and a normalised version of the telluric corrected spectrum Metaspec.dat provides the main parameters describing the spectra and the corresponding targets. meta-cal.dat provides the links between the spectral library and the calibration observations used for the instrument response correction. The information provided in this file was also reflected in the primary header of the spectra. metagaia.dat contains the result of the cross-matching of our dataset with the table gaia_source of Gaia-DR3 using a cone search of 3 arcsec for 1592 Melchiors stars.
