"The University of Michigan and OCLC today announced that they have successfully transitioned the OAIster database to OCLC to ensure continued public access to open-archive collections, and to expand the visibility of these collections to millions of information seekers through OCLC services.

OAIster records are now fully accessible through WorldCat.org, and will be included in WorldCat.org search results along with records from thousands of libraries worldwide that add their holdings to WorldCat. OCLC plans to release a freely accessible, discrete view of the OAIster records in January 2010 through a URL specific to OAIster."
