Criteria for identifying supernova remnants (SNRs) in the Galaxy and in nearby galaxies are discussed. The expected angular sizes of extragalactic SNRs are examined, along with their radio and optical brightness, properties of the 14 known SNRs in the Magellanic Clouds, and the expected angular sizes and radio fluxes of SNRs in seven nearby galaxies. The identification of three SNRs in M33, two candidates in NGC 2403, and one SNR in NGC 604 is described. The use of SNRs as an indicator of galactic chemical composition is considered, and chemical-composition determinations based on SNRs and H II regions are compared for the Galaxy, the Magellanic Clouds, and M33. It is shown that the trend in abundance variation is the same for the two types of object.
