Variable FieldsAnchor D D
Use the following table to determine what data elements should appear in the record. All other MARC variable fields are optional for abbreviated level records defined by this procedure. If other fields appear in the Voyager in-process record, use judgment to determine whether to revise or delete such fields. The guiding principles are these:
- Focus on the data elements spelled out in this procedure as mandatory or mandatory if applicable.
- Accept what is present on DLC or copy to the extent possible. Do not delete or change DLC or copy information unless it is clearly inaccurate or egregiously misleading.
- Do not agonize over data elements in a record. Make a quick decision in most cases.
