OAIster
OAIster provides access to free academic content like digitized books, articles, audio & video files, photographic images, theses and research papers. It has grown to become one of the world’s largest aggregations of records pointing to open archive collections with more than 23 million records contributed by over 1,100 institutions worldwide. OAIster was built by harvesting from open archive collections using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). From the beginning of 2002 to the end of October 2009 it was the benchmark OAI search engine project of the University of Michigan. In October 2009 OAIster’s records transitioned to the WorldCat database, which is operated by the semi-commercial library service OCLC. As of last week, an OAIster only interface is online and ready to use.
