The following source codes have been added to the Classification Scheme Source Codes list for usage in appropriate fields and elements.
The following source codes have been added to the Fingerprint Scheme Source Codes list for usage in appropriate fields and elements.
The following source codes have been added to the Genre/Form Code and Term Source Codes list for usage in appropriate fields and elements.

Two new ISSN Centre Codes, 77 for Panama and 78 for Ukraine, have now been validated for use in Bibliographic field 022 (International Standard Serial Number) subfield $2.
Validation now recognizes correct combinations of Authority 008/17, Type of Subject Subdivision (Subdiv tp), values and Authority 18X fields. Previously, validation was not accepting certain valid combinations of 008/17 codes and 18X fields.
You may now correctly validate a correctly formatted International Standard Audiovisual Number (ISAN) in the Bibliographic and Holdings fields 024 with First Indicator value 7 and the presence of subfield $2 value "isan". The structure and validation of the ISAN are described in the ISAN User Guide. Previously, ISANs that included either all zeroes in the “version” segment or any dashes were not recognized as valid.
You may now enter subfields $c and/or $d in Bibliographic field 345 without the presence of either subfield $a or $b. Previously, an incorrect validation relationship was requiring the presence of either subfield $a or $b in field 345.
You may now enter subfield $2 without the presence of subfield $b in Authority field 348. Previously, an incorrect validation relationship required the presence of subfield $b when subfield $2 was present.
