The OCLC resource sharing settings only apply to ILLiad version 9.0 and any previous versions. As of ILLiad 9.1, the OCLC Resource Sharing Settings interface was removed from within the client (the interface used to change Custom Holdings Paths, Custom Holdings Groups, Constant Data, and Direct Request Profiles) and replaced it with a button that links out to the OCLC Interface where the updated settings can be located. As a result, these settings are no longer configured in ILLiad.
To edit OCLC Resource Sharing settings such as Custom Holdings Groups and Paths, Constant Data, and Direct Request/Automated Request Manager Profiles, you'll need to login to OCLC Service Configuration using your individual staff member OCLC WorldShare account. More details can be found in the OCLC Help Article Sign in to OCLC Service Configuration or by contacting OCLC Support at 800-848-5800.
