MARC21 Update No. 35 released 21 December 2022 is now available on the MARC website. The documentation includes changes made to the MARC 21 formats resulting from proposals which were considered by the MARC 21 community since the publication of Update No. 34 (July 2022), including the joint proposal from the ISSN International Centre and the National Finnish Library about the Field 856. There is now a subfield to track persistant identifiers ($g) as well as a subfield for non-functioning URIs ($h). Changes and new text appear in red on this page.
