OCLC is a nonprofit global library cooperative providing shared technology services, original research and community programs. Through OCLC, member libraries produce and maintain WorldCat, the most comprehensive global network of data about library collections. Libraries gain efficiencies through WorldShare, a set of library management services on a cloud-based platform. Wise(tm) is the first community engagement system built for public libraries. Together as OCLC, we make breakthroughs possible.
