Definition

Media type reflects the general type of intermediation device required to view, play, run, etc., the content of a resource. Used as an alternative to or in addition to the coded expression of Media type in field 007 subfield ǂa. Field 337 information enables indication of more specific media types and media types from various lists.

Multiple media types should be recorded in separate occurrences of field 337.

If the term appearing in the field is from a translated version of the original source document or list, the code must be followed by the appropriate 3-character MARC language code from the MARC Code List for Languages (http://www.loc.gov/marc/languages). The language code is separated from the subfield ǂ2 code by a slash ( / ). The term in subfield ǂa and the language code in subfield ǂ2 should be consistent with the language coded in field 040 subfield ǂb.
