With which ILSs does WorldCat Local work?

OCLC has completed integration of WorldCat Local with several integrated library systems, and continues to work on interoperability with other systems. WorldCat Local is currently active at libraries with the following systems:

  • Innovative Interfaces: Millennium, INNOPAC, INN-Reach
  • SirsiDynix: Horizon, Symphony, Unicorn
  • ExLibris: Voyager, Aleph
  • Axiell: OpenGalaxy Plus

Expanded access to other ILSs will be added in phases.

How does OCLC support a library that migrates from one automation system to another?

Libraries are required to give OCLC 90 days notice prior to migrating to a new system. OCLC will then work with library staff to transition their use of WorldCat Local to their new service. When a library adopts a new local system for which WorldCat Local has not been configured, OCLC will make reasonable efforts to develop interoperability with the system.

How does OCLC obtain circulation information from my ILS?

Circulation information including item location, call number, status and OPAC links is retrieved from your local OPAC using screen scraping or Z39.50. The method used depends on information available to OCLC about your library's current services.

WorldCat Local "quick start" and WorldCat Local communicate with ILSs using the OCLC control number in catalog records. For this reason, your library must index the OCLC control number in a consistent manner with consistent prefixes in order for the system-to-system communication to occur.

Starting February 16, 2011, OCLC will store your local system bibliographic numbers when you do a batchload project as a way for WorldCat Local to communicate with your local system.

How is shelf status displayed in an ILS shared by a group of libraries?

During configuration, you may identify the locations that should be sorted to appear at the top of results lists in order to appropriately separate your library's holdings from the rest of the holdings in the shared catalog. Your staff will specify location names that will appear first in detailed record displays.
