MARC Mapping to MODS
Version 3.0

December 2003

This mapping is for use with MODS Schema version 3.0. The mapping for use with the MODS Schema version 2.0 is located online at: www.loc.gov/standards/mods/mods-mapping.html.

1. Introduction

This mapping gives equivalencies between MARC and MODS, but is not intended to be a crosswalk that allows for bi-directional conversions without some loss of data. Where multiple MARC elements are indicated for a single MODS element, if converted to MODS and then converted back to MARC, some specificity would be lost since some elements cannot be converted back to the same element from which they originated. This document is intended for use in converting MARC to MODS.

Where multiple subfields are specified or implied, data will be concatenated with a space substituted for the subfield delimiter and subfield code. Where multiple fields are indicated, each will be a separate instance of the element (with subfields concatenated).

Items highlighted in red indicate changes made to MODS in Version 3.0.
