New MARC 21 Data Elements in LC Bibliographic and Authority Records

These lists identify data elements from recent updates to the MARC 21 bibliographic and authority formats that will become valid in LC’s system no earlier than August 15, 2001. The lists are provided to assist in evaluating the impact on automated systems as these elements could be present in records distributed by the Library of Congress; they do not necessarily reflect values that will be actively supplied by LC cataloging staff.
