You can find OCLC Usage Statistics here
In the OCLC Online Service Center www.oclc.org/servicecenter , under billing information we offer the familiar "Product Code Detail" report. Once you navigate to invoices, you will see a corresponding link to each invoice link labeled "Details". If you click that link, the detail report opens.
This link takes you to the OCLC Worldshare logon for Collection Manager. We began using Collection Manager, which is a free service, in Feb. 2015.
Support materials for the WorldCat knowledge base and WorldShare Collection Manager/MARC record delivery have been combined to bring you the NEW support site.
Once you add your collection metadata, the system communicates with the WorldCat knowledge base and WorldCat to set holdings in WorldCat, output MARC records, provide links, and synchronize with your other OCLC services. WorldShare Collection Manager is included in your Cataloging or CatExpress subscription.
