MARC 21 Holdings Format

Full Level MARC 21 Record Examples

These examples reflect the application of MARC content designators in holdings records. They illustrate the following conditions:

The example records include at least the minimum data elements required to generate the display format. The display string, as specified by the standard (Z39.44 or Z39.71), is given first followed by the record as it would appear in a MARC holdings report. No linking fields (tags 004, 010-030) are recorded although links to the bibliographic record may be necessary. Field 001 contains the phrase <control number> which indicates that the record is an example only. The records lack a system-generated directory, and the system-generated portions of the Leader (LDR) are represented by asterisks (*). In all examples, Level 3 illustrates display Option B from the standard and Level 4 illustrates the preferred display for that level, Option A.
