Halton C. Arp photographed 338 views of notable peculiar galaxies and published them as his 1966 "Atlas of Peculiar Galaxies." Since then, galaxy catalogs have named 585 of the involved galaxies. This contemporary index collects names and characteristics of the involved objects for use by contemporary observers of the historical views. Introduction: The galaxies identified in Arp's Atlas of Peculiar Galaxies represent a remarkable cross-section of observing opportunities. With the wide availability of inexpensive CCD cameras and increasing aperture of inexpensive commercial telescopes, more of the Arp list is accessible to more observers. Many of the objects so catalogued were anonymous galaxies in 1966 and have subsequently been characterized and named. The NASA-IPAC Extragalactic Database (NED) provided most correlations and other sources identified others. Please refer to http://users.aol.com/arpgalaxy for further information.
