Abstract:
   We present 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 to 10000 Å with a nominal 
   resolving power of 12,000. 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 (Halpha to Hepsilon), Ca II H & K, the Mg
   I b triplet, Na I D_1, D_2, He I D_3, and Ca II IRT lines. There are also 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 goal 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, logg, [Fe/H]). A digital version of all the 
   fully reduced spectra is available via ftp and the World Wide Web (WWW) in 
   FITS format.
