OCLC Bibliographic Data Sync

OCLC Bibliographic Data Sync

Overview of Data Sync collections

Data Sync collections determine how records are handled during processing. Most records are processed by the General collection which uses standard Data Sync matching and field transfer options. Manuscripts and Locally digitized collections receive special handling as described in the column for Data Sync processing below.  Reproductions have a separate collection so we can ensure that OCNs output from Data Sync are only added to holdings for the reproduction format, not to the bib record.

Manuscripts

Local Field 951 contains "OCLC Data Sync manuscripts workflow". Field 951 is created in bibs automatically on save when the record meets the following criteria: (LDR/06 = d or f or t ) OR (LDR/08 = a) OR (040 $e = amim or appm or dacs or dcrmg or dcrmm or dcrmmss) AND (502 Thesis note is not present AND (533 Reproduction note is not present)

Excludes: Holdings for reproductions and locally digitized 

Trusted partner processing. Bibs in this file are eligible to replace matching master record in WorldCat if: OCLC number matches, Date on File in 008/00-05 matches, and the holding library OCLC symbol is the same as the OCLC symbol in transcribing agency, 040 $c.

Monthly on the 1st

  • OCNs loaded to bibs and holdings

Reproductions 

843 $a contains Microfilm or Microfiche or Electronic reproduction AND 014 Holdings OCN field does not exist 

Excludes: NET holdings for locally digitized

All matching where Form of item coding prevents format mismatch. Reproductions have a separate collection because OCNS for reproductions are only loaded to Alma holdings, not bibs.

Monthly on the 1st

  • OCNs loaded to holdings only

Locally digitized

852 $b = NET AND 852 $c = (GEN, IAHML, WAX,  RDM, BDRC, ETD)  AND 506 Restrictions on Access Note indicates unrestricted access AND 856 $u contains an URN indicating locally digitized

Customized field transfer instructions. All matching where Form of item coding prevents format mismatch. In matching records fields 538, 583, 506 and 856 from the Harvard record add to the master record.

Monthly on the 1st

  • OCNs loaded to holdings only

  • Future SRS project plans: Remove 540 if 845 field exists, then change 845 to 540, need |5 (added by CB 4/1/25)

  • Create Local System Number (LSN) by combining MMSID and Holdings PID

  • Change library code to USMARC code for the library

  • If 040 doesn't exist, create the field with USMARC code for the library in |a and |c

Rules applied to locally digitized:

  • If 856 second indicator is 1, change it to 0

  • Append subfield |5MH to holdings fields 506, 538, 583, 843 (533?), future SRS project plans - need to add 540/845 (added by CB 4/1/25)
