This catalog contains a high resolution atlas of both northern and southern sky symbiotic stars. It represents an all-sky optical survey of symbiotic stars using Echelle spectrometers. A summary of the stars with positions and a summary of spectra available are included. The wavelength resolution is better than 0.01 nm. The emission lines in this catalog were chosen to allow the determination of global values for the density and temperature of the nebula, as well as the temperature of the ionizing source. Note that some of the spectra with date marked by "++++" in the "ObsDate" column of the "spectra.dat" file are not in the original publications (mostly "low resolution" spectra)
