We present a complete library of synthetic spectra based on Kurucz's codes that covers the 2500–10 500 Å wavelength range at resolving powers $R_{\rm{P}}=20\,000$, 11 500 (≡GAIA), 8500 (≡RAVE), 2000 (≡SLOAN) and uniform dispersions of 1 and 10 Å/pix. The library maps the whole HR diagram, exploring 51 288 combinations of atmospheric parameters spanning the ranges: 3500 $\leq T_{\rm eff} \leq 47\,500$ K, $0.0\leq \log g \leq 5.0 $, $-2.5 \leq {\rm [M/H]} \leq 0.5$, [ α/Fe] = 0.0,+0.4, ξ = 1, 2, 4 km s-1, 0 $ \leq V_{\rm rot} \leq$ 500 km s-1. The spectra are available both as absolute fluxes as well as continuum normalized. Performance tests and spectroscopic applications of the library are discussed, including automatic classification of data from spectroscopic surveys like RAVE, SLOAN, GAIA. The entire library of synthetic spectra is accessible via the web.
