Description/Instructions

Field 051 is used to record information relating to additional copies, issues, offprints, detached copies, etc., which are added to the catalog record at the Library of Congress. The field does not include supplements, indexes, etc., which are related to, but not the same as, the work in the main record. This field is frequently used for Library of Congress publications when the first two copies are given a call number based on the subject of the publication and additional copies are given a call number assigned to Library of Congress publications.
