Hello - I encountered this name in the NAF (ARN 255855, 010 n 79022059) 100 1_ Finkelstein, Louis, ǂd 1895-19911129 Sure, we use ISO 8601 for the dates in the 046 field. But I have never heard of using that style in 100 $d. What I've seen is this style: 1991 November 29. Is there a new PCC standard for 100 $d dates that I have overlooked? Thank you for any light you can shed. -- Ann Heinrichs Metadata/Cataloging Librarian The Paul Bechtold Library Catholic Theological Union 5401 S.
