Subject Terms:	*Libraries, Unicode (Computer character set), Ciphers, Latin language, Databases, MARC formats, Chinese language, Japanese language
Abstract:	The article discusses the effects of the use of unicodes in the MARC 21 records. Specifically, it tries to highlight the accommodation of the greatly expanded character repertoire that includes not only additional non-Roman scripts but many more Latin script characters. MARC 21 is flexible with respect to the structure of records containing multi-script data to accommodate different needs worldwide. MARC 21 has specified two record models designated as A and B. Model A is a record in the preferred script which can be augmented with specially designated fields holding other scripts and Model B is a record which can have data in any script in regular fields. Model A is largely used for the MARC 21 bibliographic records with Latin as the preferred script. Model B can be seen by libraries with devices capable of displaying Chinese, Japanese, and Korean. It is necessary for a Model A record encoded in Unicode with Latin to be the preferred script that the definition of the Latin script data content of regular fields should be controlled by the Script Names property of Unicode. Creating consistent records for MARC 21 interchange necessities the data content in Model A records with Latin as the preferred script should be controlled.
