These data are of high resolution (0.13 A at 6100 A) and high signal-to-noise. The spectral range spans from 5080 to 7850 A; however, there are gaps due to the unmatched size of the echelle format and the charge coupled devices (CCD). We have observed a total of 87 carbon stars in the solar neighborhood over the period from 1988 May through 1991 September, with two or more observations for 67 stars of the sample. The reduced spectra (40 orders per observation for a total of nearly 9200 individual spectra) will be available to the scientific community via the Astrophysics Data System (ADS). The current study has produced the most detailed multi-epoch observations to date of a large number of carbon stars. Presented here, along with spectra of the six sample stars, are separate template plots to be used as a tool for the ADS on-line database. These templates are of atomic features, as well as (12)CN and (12)C2 transitions taken from the tables of Davis & Phillips (1963) and Phillips & Davis (1968), respectively. We have calculated band head positions for the isotopic species (13)C (14)N, (12)C (13)C and (13)C (13)C, whose transitions contribute significantly to the spectra of carbon stars with enhanced C-13 abundance, known as J-type carbon stars.
