Codes for languages associated with the entity described in the record. Includes the language a person uses when writing for publication, broadcasting, etc., a language a corporate body uses in its communications, a language of a family, or a language in which a work is expressed.
If the Bibliographic format is used to represent a work or expression with no manifestation information, follow these guidelines to use field 377 in relation to fixed field element Lang, field 041 and field 546:
Lang. The fixed field element Lang supports primarily machine indexing of the language of the resource for user tasks to find and select. Always supply Lang for a resource/manifestation or an expression, but do not supply if the record is for a work.
041. Supply 041 as needed and as applicable in bibliographic records for the manifestation only; do not use if the record is for a work or expression.
546. Use 546 to record textual information about language in bibliographic records for the manifestation or expression; do not use if the record is for a work.
377. When the resource description is for an expression, the 377 can be supplied even when one 377 duplicates the language information in the heading ‡l. In an expression description, Lang and field 546 may also contain language information.
