CJK Compatibility Database

The CJK Compatibility Database includes more than 450 non-MARC21 Chinese, Japanese and Korean characters, Hangul syllables and diacritic marks, matched with their MARC21 equivalents.The database is intended to enable catalogers to quickly and conveniently replace a non-MARC21 character with its MARC21 equivalent.The list of characters in the database was initially identified by LC staff, and was supplemented by entries in a similar database at Yale University.The database is a cooperative undertaking, and is intended for the use of all CJK catalogers. If you encounter a non-MARC21 character in the course of your work, please report it to us so that it can be added to the database.
