Streamline electronic resource workflows

The WorldCat knowledge base combines data about your library’s electronic resources with linking features to make your collections easier to find, use and manage. The WorldCat knowledge base also helps you streamline electronic resource workflows.  

Unlike data in a traditional knowledge base, WorldCat knowledge base data is not tied to a particular application. When you register your collections in the WorldCat knowledge base, you enable key functionality in numerous OCLC services, including:

  • Automatic management of WorldCat holdings and delivery of WorldCat MARC records for electronic materials
  • Easy access to e-resources in search results, OpenURL link resolution, and A-Z search and browse of databases and journal titles
  • Quick and easy sharing of your electronic content
  • Manage budgeting, ordering and acquisition of electronic resources
  • Rights management, usage statistics and link resolution of electronic materials
