As we first noted in the August 2013 release notes, the WorldCat knowledge base currently supports two user interfaces:
Since supporting multiple interfaces requires more resources and effort, we are going to start actively transitioning everyone to the WorldShare interface so that we can focus all of our development efforts in one place and bring users more and better features more quickly.
Note that this announcement relates only to the WorldCat knowledge base section inside of Service Configuration. Other modules, such your library information in the WorldCat Registry, will continue to be administered through the Service Configuration interface.
While you wait for OCLC to contact you with your WorldShare account information, you can explore the documentation and training materials available for the WorldShare interface to help familiarize yourself with the features unique to the WorldShare interface. For example, see:
If you are getting an account for the WorldShare interface for the first time, note that you will need to set a password after receiving your information from OCLC. To create additional WorldShare accounts, see the instructions for managing staff accounts in the WorldShare interface. This web resource includes the authorizations needed to allow an account owner to edit metadata in your knowledge base.
