We present here a library of Penn State Fiber Optic Echelle (FOE) observations of a sample of field stars with spectral types F to M and luminosity classes V to I. The spectral coverage is from 3800 AA to 10000 AA with nominal resolution 12000. These spectra include many of the spectral lines most widely used as optical and near-infrared indicators of chromospheric activity such as the Balmer lines (H to H_epsilon), Ca II H & K, Mg I b triplet, Na I D1,D2, He I D3, and Ca II IRT lines, as well as a large number of photospheric lines, which can also be affected by chromospheric activity, and temperature sensitive photospheric features such as TiO bands. The spectra have been compiled with the aim of providing a set of standards observed at medium-resolution. We have extensively used such data for the study of active chromosphere stars by applying a spectral subtraction technique. However, the data set presented here can also be utilized in a wide variety of ways ranging from radial velocity templates to study of variable stars and stellar population synthesis. This library can also be used for spectral classification purposes, and determination of atmospheric parameters (T_eff}, log{g}, [Fe/H]). A digital version with all the fully reduced spectra is available via ftp and the World Wide Web (WWW) in FITS format.
