Dragonfly Summer 2003 -- Volume 34, Number 3

First SERHOLD-to-OCLC Batch Update Is a Success!

by Susan Barnes, Resource Sharing Coordinator
NN/LM Pacific Northwest Region

The processing for the first SERHOLD to OCLC batch update was completed on Saturday, August 16th. Of the 166,100 eligible records, OCLC successfully updated 165,764 Local Data Records (LDRs) in WorldCat for 271 libraries. NLM is very pleased that more than 99% of the holdings loaded with our first SERHOLD to OCLC batch update!

Here's the summary breakdown for the 336 records that were not processed:

• 170 Encoding Level 2: no volume or year data
• 138 Unbalanced Enumeration/Chronology: the number of volume statements does not match the number of year statements
• 21 Incorrect Acquisition Status: the acquisition status was 4 (currently receiving), but the holdings statement had ending volume or ending year data
• 4 Volume/Year statements exceeded the maximum allowed in OCLC
• 2 Invalid Year data
• 1 Invalid OCLC Number -- NLM is looking into this one

Your DOCLINE/SERHOLD coordinator will provide you with a list of holdings that need to be updated if holdings for your library were rejected for any of the above reasons. As you correct these records in SERHOLD, they will be provided to OCLC when the next SERHOLD data extract is performed (October).

Now that we know certain categories of holdings will be rejected, we will work on additional SERHOLD error reports that will assist you in cleaning up your holdings.

Additional information can be found in the following FAQs and sections of Help:

• How do I authorize NLM to send a copy of my library's holdings records to OCLC?
  ( http://www.nlm.nih.gov/services/doc_batch_update_serholdtooclc_docuser_update.html)
• What is the schedule for SERHOLD to OCLC Batch Update?
  (http://www.nlm.nih.gov/services/doc_batch_update_serholdtooclc_schedule.html)
• SERHOLD Level 2 Holdings Report
  (http://www.nlm.nih.gov/docline/docline_manual/serhold/report_level_2_holdings.html)

If you have not yet signed up for SERHOLD-to-OCLC Batch Update, now's the time! Here's what to do:

1. If your library has been deleting records from OCLC when titles have been removed from your library's collection, authorize NLM to send your holdings to OCLC by doing the following:

a. Within DOCUSER, click on the Codes Tab.
b. If there is no value in the OCLC Symbol 1 field, input your OCLC Symbol.
c. If you have values in OCLC Symbol 2 and/or OCLC Symbol 3, remove them. Holdings can only map to one OCLC Symbol.
d. Select "NLM is authorized to send a copy of my library's holdings to OCLC" from the Batch Update Authorization field.

The holdings will be provided to OCLC after the first weekend of January, April, July, and October.

(Unfortunately, libraries that are part of a larger institution with one OCLC code and with multiple holding library codes for each "branch" can not participate in this service. The batch transfer would delete holdings for all units that share that same OCLC code. For details, see http://www.nlm.nih.gov/services/doc_batch_update_serholdtooclc_multiple_oclcids.html)

2. If your library has not been deleting records from OCLC when titles have been removed from your library's collection, you should delete holdings in OCLC that you have already deleted in SERHOLD. The first time your library participates in the SERHOLD to OCLC batch update program, NLM recommends deleting records from OCLC for holdings which have been deleted from SERHOLD. It is possible that there were multiple holdings records in DOCLINE for the same title or that a holdings record was deleted and then later added back to SERHOLD. Therefore, if you delete holdings in OCLC after, instead of prior to, the SERHOLD to OCLC batch update extraction, it is important to compare the list of deletes to the current holdings in SERHOLD and only make the appropriate deletions from OCLC.

To obtain a list of all records deleted from SERHOLD since June 2000, please contact your Region's SERHOLD Coordinator who will work with NLM to generate the list. Here in the Pacific Northwest, that's Susan Barnes at sjbarnes@u.washington.edu or 1-800-338-7657 (from AK, ID, MT, OR, and WA).
