The University of Michigan and OCLC will jointly support the OAIster search engine for open access documents.
Here's an excerpt from the press release:
Launched in 2002 with grant support from the Andrew W. Mellon Foundation, OAIster was developed to test the feasibility of building a portal to open archive collections using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). OAIster has since grown to become one of the largest aggregations of records pointing to open archive collections in the world with over 19 million records contributed by over 1,000 organizations worldwide.
Under the partnership, OAIster.org will continue to function as the public interface to OAIster collections, through funding provided by OCLC to the University of Michigan. Later in 2009, metadata harvesting operations will transfer from the University of Michigan to OCLC. . . .
Starting in late January 2009, while OAIster continues to be freely available at the www.oaister.org Web site, OCLC will host a version of OAIster on OCLC's FirstSearch platform and make it available through subscriptions to the FirstSearch Base Package at no additional charge.
