A number of changes to OCLC-MARC have been reported in TB 254. These are based on changes made to MARC 21 in October 2005. Hmm, a year and a half lag time: not bad OCLC!
Some highlights include:subfields in 020 now non-repeatable
- new subfield ’2′, ‘Source of code’ in 048
- new 1st indicator values and subfields ‘f’ and ’2′ in 506
- new 1st indicator value and subfield ’8′ in 590
- new relator code subfields in 6XX fields
