MARC 21 Data Elements in LC Bibliographic and Authority Records
This list identifies data elements from Update no. 2 (October 2001) to the MARC 21 Formats for Bibliographic and Authority data that will become valid in LC's system no earlier than September 1, 2002 (unless otherwise specified below) and other information related to MARC 21 data elements of interest to subscribers.
1. NEW BIBLIOGRAPHIC RECORD ELEMENTS
This list is provided to assist in evaluating the impact on automated systems as these elements could be present in records issued by the Library of Congress; they do not necessarily reflect values that will be actively supplied by LC cataloging staff. These elements are fully documented in the MARC 21 Format for Bibliographic Data (http://www.loc.gov/marc/bibliographic).

2. NEW AUTHORITY RECORD ELEMENT
This information is provided to assist in evaluating the impact on automated systems as this element could be present in records issued by the Library of Congress; this does not necessarily mean that the element will be actively
supplied by LC cataloging staff. This element is fully documented in the MARC 21 Format for Authority Data (http://www.loc.gov/marc/authority).
043 - Geographic area code
new subfield: c (ISO code)
3. BIBLIOGRAPHIC ELEMENTS FOR FUTURE IMPLEMENTATION
The following changes from Update No. 2 (October 2001) to the MARC 21 Format for Bibliographic Data will not be implemented at the Library of Congress at this time. A future notice will be issued when implementation details have been set.
LEADER/07 (Bibliographic level)
new code: i (Integrating resource)
SERIAL 006/01, 008/18 (Frequency)
new code: k (Continuously updated)
SERIAL 006/04, 008/21 (Type of continuing resource)
new codes:

l (Updating loose-leaf)
w (Updating Web site)
SERIAL 006/17, 008/34 (Entry convention)
new code: 2 (Integrated entry)
260 - Publication, distribution, etc. (Imprint): change from non-repeatable to repeatable
define first indicator (Sequence of publishing statements) with values:
[blank] (Not applicable/No information provided/Earliest available publisher)

3 (Current/latest publisher)
4. ELEMENTS TO BE ISSUED IN NON-SERIAL RECORDS
Because the new bibliographic level "integrating resource" will not be implemented at this time (see 3. above), records for integrating resources will continue to be coded as monographs (Leader/07=m). However, since the Library of Congress plans to implement revisions to Chapter 12 "Continuing Resources" of AACR2 on December 1, 2002, subscribers will begin to see content designation in monographic records after that time that heretofore has appeared primarily in only serial bibliographic records:
022 - International Standard Serial Number
222 - Key title
247 - Former title or title variations*
310 - Current publication frequency
321 - Former publication frequency
362 - Dates of publication and/or volume designation
547 - Former title complexity note*
550 - Issuing body note
580 - Linking entry complexity note
76X-78X - Linking entries
*Indicates fields formerly found only in pre-AACR2 serial bibliographic records.
