OCLC is a nonprofit global library cooperative providing shared technology services, original research and community programs. Through OCLC, member libraries cooperatively produce and maintain WorldCat, the most comprehensive global network of data about library collections and services. Libraries gain efficiencies through OCLC’s WorldShare, a complete set of library management applications and services built on an open, cloud-based platform. Together as OCLC, we make breakthroughs possible.
