Replaced represents the date of the last replace transaction. Replace transactions include replaces done by batchloading processes and changes to the record made as a part of database quality activities. These transactions result in a change in the Replaced date. Such changes are not always reflected in field 040 subfield ǂd.

For a record created online by a member institution, Replaced is the same as the Entered date until a subsequent replace transaction occurs.

For a batchloaded record, Replaced represents the date on which that record was loaded into WorldCat, until a subsequent replace transaction occurs.

If the system replaces a member-input with a batchloaded record, the Replaced date reflects the date on which the record was replaced. The Replaced date could change again if another replace transaction occurs.
