{"apiVersion":"2.1.0","data":{"description":"This document is intended for use in converting MARC 21 bibliographic records to MODS. Where multiple subfields are specified or implied in MARC, data will be concatenated with a space substituted for the subfield delimiter and subfield code. Where multiple MARC fields correspond to a single MODS element, each will be mapped to a separate instance of the element (with subfields concatenated). Because of this, it is not generally possible to perform a round-trip conversion without loss of specificity.","locations":[{"type":"document","url":"http://www.loc.gov/standards/mods/v3/mods-mapping-3-6.html"},{"type":"library (XML)","url":"http://www.loc.gov/standards/mods/v3/MARC21slim_MODS3-6_XSLT2-0.xsl"}],"mscid":"msc:c28","relatedEntities":[{"data":{"description":"MARC is a standard and serialization format for representing bibliographic metadata, originally designed as a way of exchanging bibliographic records between library catalogs.
