MARC to BIBFRAME Comparison Service

This service produces a comparison of a MARCXML record and its BIBFRAME representation. Currently it only accomodates Library of Congress MARC records. Enter the BIBID of a Library of Congress record into the box. The BIBID is carried in the MARC 001 of the Library of Congress record. (It is not the LCCN which is in the MARC 010.)
