OAIster is a union catalog of millions of records representing open access resources that was built by harvesting from open access collections worldwide using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Today, OAIster includes more than 25 million records representing digital resources from more than 1,100 contributors.
WorldShare Metadata will provide a complete metadata management solution for physical, licensed and digital resources across multiple formats. This set of new applications and services will be made available in phases over the next few years. The changes are part of OCLC's strategy to provide Webscale solutions to the full range of library management needs, including acquisitions, license management, resource sharing and discovery.
