I realized recently that all our bibliographic records have the Modification Date populated, even new records. It turns out that the process of creating the record will update the Modification Date due to an aspect of the process. This doesn't seem part of the intended design, so it would make sense to correct the process to stop adding a Modification Date entry.

This may cause confusion for staff working with bib records, and in general it's not good from a record metadata quality perspective to have misleading modification details. It can be filtered around in queries (the modifier isn't populated, and the creation and modification dates would match), but requires the person running the query to know about this being a facet of the data.
