Fact Sheet
SERHOLD®

SERHOLD is the National Library of Medicine's (NLM) database of machine-readable holdings statements for biomedical serial titles held by U.S. members of the NLM-supported National Network of Libraries of Medicine® (NN/LM®) as well as selected Canadian and Mexican libraries. These holdings statements are linked to NLM's authoritative bibliographic data in LocatorPlus. As of August 2004, the database includes over 1.4 million holdings statements for 53,761 serial titles from 3,089 health sciences libraries in the United States, Canada, and Mexico.

Each of the eight Regional Libraries in the NN/LM is responsible for the coordination of updates to SERHOLD for its region. CISTI, Canada Institute for Scientific and Technical Information, the Canadian MEDLARS® Center, coordinates the SERHOLD updates for Canada. Centro de Información Para Decisiones en Salud, the Mexican MEDLARS Center, coordinates the SERHOLD updates for Mexico. NLM distributes SERHOLD data only to participating institutions.

Access to SERHOLD

Only DOCLINE® participants have access to SERHOLD via the DOCLINE Serial Holdings module. Libraries that wish to become DOCLINE participants should review the Eligibility Guidelines for new DOCLINE Libraries. Once libraries become DOCLINE participants, they will receive a USERID and password for the DOCLINE system.

Titles Included

Participants are limited to reporting holdings for serial titles that are in NLM's LocatorPlus database. This database contains over 100,000 serial titles. The database has been augmented by the addition of non-NLM titles held in the NN/LM regions. Titles are reported to NLM with appropriate bibliographic documentation and added to LocatorPlus if they are available for interlibrary loan and provide information needed by health care professionals and health sciences library personnel in the course of their work. Serials designed for recreational reading will not be included. To make requests to add a title to LocatorPlus or to request changes to the bibliographic data, review the Policy Statement on the Addition of Non-NLM Titles to the NLM LocatorPlus Database for SERHOLD Reporting.

Updating Holdings Data

Since DOCLINE can route on holdings information as soon as it is added or modified, NLM encourages all DOCLINE participants to add, modify, or delete holdings for their own library using the DOCLINE Serial Holdings module of the DOCLINE system. To eliminate the need for updating holdings data in both DOCLINE and OCLC, NLM now offers quarterly data tranfer from SERHOLD to OCLC via the batch update function. In addition, NLM can import serial holdings data from OCLC into SERHOLD when a library's OCLC union list product, referred to as "SULOP" (Serials Union List Offline Product) by OCLC, is produced. The first SERHOLD to OCLC batch update file, which consisted of holdings for all libraries that had authorized NLM to provide the data to OCLC, was delivered to OCLC in July 2003. The first OCLC to SERHOLD batch update was processed in June 2004. NLM provides additional information regarding batch update in the SERHOLD Batch Update FAQs.

Products

Each participating library can produce a list of its own holdings on demand. Participants are also able to view union lists of holdings for libraries in their own library group and in their own state or province. These union list products are updated quarterly.
