This list was originally compiled in collaboration with Library of Congress MARC Pilot Project participants, the National Library of Medicine, the National Agricultural Library, and the Defense Language Institute.  In addition, the language list of the Center for Applied Linguistics, Library of Congress Subject Headings (LCSH), and language specialists were consulted.  The list was revised by a committee of the National Information Standards Organization (NISO) and became an American National Standard in 1987:  Codes for the Representation of Languages for Information Interchange (ANSI Z39.53).  In 2000, the list was further revised to include numerous changes necessary for compatibility with the ISO 639-2 (Codes for the Representation of Names of Languages Part 2: Alpha-3 Code) standard.
