CAT DATE in Imported records from databases other than LA

From email from Ross 25/2/09
The 008 date entered remains the same as the source record for copy cataloguing including copy from other databases, even if significant changes are made to the record (CIP upgrade etc) as long as it represents the same edition, and keep the 040 etc.
(Strictly speaking we should change leader 000 field position 5 (first editable code) from n to c [or a or p] when we do such a change to a record but I have never insisted on this, as to be consistent we would then also need to comply when updating LA copy etc, which is a bit much to expect anyone to do!)

For new records including cloned new records based on other edition, use new date entered (and 040 WMDU)
