Language Code and Term Source Codes
Introduction
Language Source Codes
Language Source Code Usage in MARC and
MODS/MADS
Introduction
Language Sources contains a list of standard language code and/or term sources and assigns a code to each. The purpose of this list is to enable the source of language codes or terms contained in metadata records to be identified. For code assignment, general structure, usage, and maintenance guidelines see Source Codes for Vocabularies, Rules, and Schemes.
Arrangement of the List
Entries in the list are arranged in alphabetical order by the code and consist of the source code followed by the bibliographic citation for the source documentation. The citations are linked to the online source for some codes.
Code Structure
Each code consists of a maximum of 12 characters, including lowercase alphabetic characters, numeric characters 0 through 9, and the hyphen (-). Possible additions to codes are described in Source Codes.
