+The '''Internet Archive ARC''' format is different from and not compatible with the (at one point) better-known [[ARC (compression format)|ARC]] format popular on bulletin board systems in the 1980s (nowadays, the Internet Archive one may be better-known in the archiving community, while neither format is probably well known to the general public).

 The '''Internet Archive ARC''' format has a successor format, [[WARC]] (ISO 28500:2009, Information and documentation -- WARC file format).
