ISO 233-2:1993 is an ISO schema for the simplified transliteration of Arabic characters into Roman characters.
This transliteration system was adopted as an amendment to ISO 233:1984. It is used mainly in library context, and was introduced because ISO 233 was not meeting the indexing purposes, which are essential for the consistency of library catalogs.
According to ISO 233-2(1993), Arabic words are vocalized prior to romanization.
ISO 233-2 is used in French libraries, in North African libraries, and is recommended by ISSN for establishing key titles when cataloguing serials.
