Comment 3 for bug 1828279

+1 for this feature. This would be particularly awesome in large consortia like PINES where we all own the same record and there are many catalogers with access to edit the record.

There's already auditor.biblio_record_entry_history (http://docs.evergreen-ils.org/3.1_schema/_schema_auditor.html#_biblio_record_entry_history) which pretty much has what I'd be interested in seeing. We would just have to figure out how to only show the difference in the marc column between two edits, and doing the color styling to show additions/subtractions.
