DOCLINE -- SERHOLD to OCLC Batch Update Overview
Question: What is SERHOLD to OCLC Batch Update?
Answer:
- It is several programs that were written by both NLM and OCLC to take holdings from DOCLINE Serial Holdings and load them into OCLC. It enables libraries to enter holdings into DOCLINE Serial Holdings and not have to rekey the same information into OCLC.
- The holdings of all libraries that authorize NLM to send Serial Holdings to OCLC by changing their Institution record, Membership page, Serial Holdings section, Batch Update Authorization field to "Send Holdings to OCLC", will be placed into a file and sent to OCLC once per quarter at the same time that the Library Group Union List products are generated the first weekend of the month in January, April, July, and October.
- All holdings are extracted for the first update and provided to OCLC. OCLC adds these holdings to their database or updates the holdings in their database. No records that have been deleted from DOCLINE Serial Holdings are provided to OCLC with the first extraction. If a library does not change their authorization, only holdings that have been added or modified and holdings that have been deleted are provided to OCLC after the first extraction for that library; holdings that have not been changed or deleted will not be provided to OCLC a second time.
- After the holdings that NLM provides to OCLC are extracted, NLM notifies libraries via DOCLINE Serial Holdings Reports of any known errors. It is up to the individual library to add these problem holdings to OCLC, to add a bibliographic record to OCLC when appropriate, and/or to notify NLM of OCLC numbers when the OCLC number is not in the LocatorPlus record. Instructions about each type of problem are located at the beginning of the error reports. Error reports will only be supplied when there are known errors. If OCLC notifies NLM of any problem records after the data are loaded, NLM will notify the appropriate Regional DOCLINE Coordinator who will then contact the individual library.
- OCLC uses the following data elements from the DOCLINE database to create OCLC Local Data Records (LDRs) that are added or updated in WorldCat through batch processing. If a field is in OCLC, but is not listed below, it will be null in OCLC after the batch update has occurred.
- OCLC Number
- OCLC Symbol 1
- LIBID
- NLM Unique ID
- Holdings
- Retention Policy
- Acquisition Status

- If your library has not been deleting holdings from OCLC and you would like a listing of all records that have been deleted from DOCLINE Serial Holdings since June 2000, please contact your Regional DOCLINE Coordinator who will work with NLM to provide you with that information.
