A library of 183 588 synthetic spectra based on Kurucz's ATLAS9 models is presented for the far red spectral interval (7653-8747 Å). It is characterized by K, , , km s-1, km s-1. The whole grid of spectra is calculated for resolving powers 8500, 11 500 and 20 000. A section of the grid is also computed for [ and for microturbulent velocities 0 and 4 km s-1. The library covers the wavelength ranges and resolutions of the two ambitious spectroscopic surveys by the ground experiment RAVE and the space mission GAIA. Cross-sections across the multi-dimensional data-cube are used to illustrate the behaviour of the strongest spectral lines. Interpretation of real data will have to include interpolation to grid substeps. We present a simple estimate of the accuracy of such a procedure.
