How do I filter records based on the MARC 005? DATE AND TIME OF LATEST TRANSACTION biblio.timestamp doesn't do it. This is what I have: SELECT biblio.biblionumber,items.barcode,biblio.author,biblio.title,biblio.timestamp,biblio.datecreated FROM items LEFT JOIN biblioitems on (items.biblioitemnumber=biblioitems.biblioitemnumber) LEFT JOIN biblio on (biblioitems.biblionumber=biblio.biblionumber) WHERE biblio.timestamp >= '2014-05-01' AND biblio.timestamp <= '2014-05-30' ORDER BY biblio.biblionumber asc In the guided report the option I chose was Modification date / biblio.timestamp But after testing this I've discovered that it isn't using the date in the 005. I'm not sure where the Modification date / biblio.timestamp information is coming from, it's neither the creation date, nor the modification date, but some other date entirely. I'm trying to hunt down a batch of records modified on a certain date.
