Optical spectra of supernova remnants

1976 Publications of the Astronomical Society of the Pacific  
Montages of red and blue image-tube spectra are presented for 21 different supernova remnants located in the southern Milky Way and in the Magellanic Clouds. Particular spectral characteristics are described for each remnant and some new emission lines are tentatively identified. Attention is drawn to the apparently radio-quiet objects N70 and N185 in the LMC, and a case is made for their being supernova remnants.
