NTL / MARC VARIABLE FIELD MAPPINGS

The National Transportation Library has created this crosswalk from NTL’s extended Dublin Core metadata to MARC to make NTL data more accessible to other libraries and information sources.

Note: Whenever possible, NTL field names are used in the underlined headings. If a heading is in square brackets, it does not have a corresponding field name. Items in bold are NTL field names.
