MARC Report 250: MARC Changes

An objective of MARC Report 250 is to support the changes introduced by–

MARC21 Update No. 25--Bibliographic
MARC21 Update No. 25--Authorities

–announced by LC on December 18, 2017.

This update might be dubbed the “dollar $1 update”, since the main thrust of this update is to define $1 as a content designator for a Real world object URI (in far too many tags to list here).

One other interesting change (from the perspective of RDA) is the addition of a new tag

758 Resource identifier

which contains, in its definition, the following statement:

Resources thus identified may include, but are not limited to, 
FRBR works, expressions, manifestations, and items.

In addition, MARC Report 250 updates its codelists to include changes added by the following:

• Addition to MARC Code List for Languages (December 21, 2017)

• Additions to Source Codes for Vocabularies, Rules, and Schemes (December 01, 2017)
