OCLC Local Holdings Updating:
What it is, How it is Done, and How it Affects You
What it is
- The new name for Union Listing
- Transfers our specific holdings fields to OCLC
- Assists ILL in filling lending requests (and evaluating borrowing requests!) accurately
- May someday be available in the WorldCat Database, or worldcat.org
How it is done
- Records are extracted and sent to OCLC, they process and batchload
- One large initial load (about 96,000 HOL records) has been sent, extracted 2006
- About 3500 records needed correction or reformatting
- An update file is being created now
- Future monthly updates are being planned
How it Affects You
- OCLC is much more particular about HOL formatting than Aleph
- All 85X/86X fields must have $8 and $a
- Sequence numbers cannot be repeated
- OCLC thinks 1.10 and 1.100 are the same sequence (reads like a decimal)
- 85X/86X and 866 cannot be used on the same record unless suppression codes are used
- 866 fields must have a $8 0
- Cleanup underway of the 3500 records
- Many records have been fixed since 2006
- Many just had missing $8 or duplicate sequence numbers
- Oldest records have the most complex problems
- Cataloging staff have been told not to change patterns unless $8 or $a are missing
