0252 002W Date of creation (yymmdd) in original database of main/master level data Date originates from tag 008 Fixed-Length Data Elements, characters 00-05 Date entered on file.

Only the date is put in this tag; the source code of the original library is not added.

The year yy is not converted into yyyy, because MARC tag 008 still uses 6 characters and not 8 for the creation date.

When there is no date, the string consists of zeros, or, when the string contains non-digits, then this tag is not used.
