OCLC-MARC Format Update 2007 — Technical Bulletin 254

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
