Data is the foundation of nearly all OCLC services, and we take pride in being a vendor-neutral technology provider.

We at OCLC recognize that businesses, the tech world, and higher education are abuzz with discussions and predictions about big data. OCLC’s APIs are powerful tools that enable libraries like yours to interact with your users and experiment with your data in new ways.
