Check this option to perform validation on all MARC fields when a bibliographic, authority, or holdings/checkin record is being created or edited. The box is checked by default. When the box is un-checked, validation is turned off for all open MARC records. When the box is checked again, validation is turned on for all open MARC records and all subsequent MARC records are validated when opened.
Refer to the Innovative Guide and Reference, Page # 105692: Validating MARC Tag Information for information about validating MARC tag information in the Millennium Editor.
OVERWRITE MARC TAGS/INDICATORS
Check this option to choose to overwrite, rather than insert, existing MARC tags and indicators when editing a MARC record. When this box is checked, placing the cursor in the MARC tag, Indicator 1 or Indicator 2 positions in a record causes the editor to be in OVERWRITE mode. When the cursor moves to the main data portion of a MARC field, the editor switches to INSERT mode.
