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.
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.

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) | |||

| new codes: | |||
| d (Updating database) | |||
| 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 | |||

| [blank] (Not applicable/No information provided/Earliest available publisher) | |||
| 2 (Intervening publisher) | |||
| 3 (Current/latest publisher) | |||
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.
