The Full Form of OCLC is‍ Online Computer Library Center.

OCLC is a global library cooperative that provides shared technology services, original research and community programs for its membership and the library community at large. We are librarians, technologists, researchers, pioneers, leaders and learners. With thousands of library members in more than 100 countries, we come together as OCLC to make information more accessible and more useful.

Whether we’re supporting advancements on the leading edge of science or helping children build a strong learning foundation, shared knowledge is the common thread. People can find the answers they need to solve important problems in their lives, in their communities and in the world. Together we make breakthroughs possible. Both big and small.
