MARC: News and Announcements (December 18, 2017)
Update No. 25 (December 2017) is now available on the MARC website (www.loc.gov/marc/). It is integrated into the documentation for each of the Online Full and Concise formats that are maintained on that site -- the Bibliographic format, Authority format, Holdings format, Classification format, and Community Information format. The documentation includes changes made to the MARC 21 formats resulting from proposals which were considered by the MARC 21 community in June 2017.
The changes are indicated in red. Each format also has an appendix,"Format Changes for Update No. 25 (December 2017)" that lists the changes that comprise the update. The Web version of the formats is the official version and its release is considered the start date for implementation planning for Update 25. Users are not expected to begin using the new features in the format until 60 days from the date of this announcement: December 18, 2017. For more information about format documentation see: //www.loc.gov/marc/status.html.
Users who want a print version of changed fields will be able to print them from the Format web pages (CDS does not sell a print version of the update). The "Format Changes" appendixes noted above incorporate a print guide following the list of changes, to facilitate easy printing.
Users may need to refresh pages on their browsers to see the changes.
