**License Manager is OCLC’s electronic resource manager powered by data in the WorldCat knowledge base. It provides a central location for managing the license terms and vendor contact information required for management of electronic resources. It includes a globally-maintained vendor information center and templates for global management of public and shared licensing terms.

Getting started

Activation of OCLC’s link resolver first requires a subscription to WorldShare Management Services, WorldCat Discovery, or License Manager. Further, the link resolver functionally requires that you have added collection metadata to your WorldCat knowledge base via WorldShare Metadata Collection Manager (included in your cataloging subscription).

See the knowledge base documentation page for the request form and for instructions on adding collections of title metadata to your knowledge base.

New users: Customizing the OCLC link resolver and integrating it with other services

Customization settings are in OCLC Service Configuration. Please note that any changes you make in Service Configuration will also be reflected in other live services that use the settings.

To configure link resolution functionality, log into Service Configuration and complete the following settings (see the OCLC Service Configuration Guide for detailed instructions):

  • Navigate to Inbound Links and A-Z - Full Text OpenURL Resolvers - incoming requests. Complete the settings for Base URL, Bypass Landing Page, and so forth
  • IP address recognition is configurable. Settings are in the IP Addresses module
  • If relevant, add a resource sharing request button so patrons can submit ILL requests using your OpenURL resolver. See the WorldCat.org - Customize Place Hold/Request Buttons settings

To share holdings with Google Scholar or to give your base URL to other providers:

  • Configure your WorldCat knowledge base to share holdings for Google Scholar search results. See Setting up Google Scholar links for help
  • Note that after you have collections in your knowledge base:
    • Your A-Z list is here: http://[library].on.worldcat.org/atoztitles
    • Your base URL for third party providers ends with /link
    • You can find your base URL in OCLC Service Configuration https://worldcat.org/config (Inbound Links and A-Z - Full Text OpenURL Resolvers - incoming requests)

Current users: How to obtain the latest version of the link resolver

Users are encouraged to migrate as soon as possible to receive the benefits of 2.1. You must follow the steps below before the end of 2014 when version 1.0 will be retired.

Some current users will have version 1.0 and others will have 2.1. Determine your current version of link resolver:

If you have version 1.0 with "openurlresolver" in the URL, follow these steps to migrate to to version 2.1:

  • Make a selection between version 1.0 and version 2.1 from the above list
  • Ensure you save the page prior to exiting OCLC Service Configuration
    Please Note: Libraries who subscribe to License Manager but not to WorldCat Discovery have only the option to save version 2.1 of the link resolver
  • If you need help, please contact OCLC support with your institution and registry ID and a description the issue encountered
  • Share your new base URL with all vendors who pass OpenURL queries to your WorldCat knowledge base
  • If you previously completed the Google Scholar settings in order to make full-text links to your library’s resources available via Google Scholar searches, you’ll need to update your URL in the settings.
