WorldCat Turns 40

WorldCat turns 40

“On August 26, 1971, the OCLC Online Union Catalog and Shared Cataloging system (now known as WorldCat) began operation. That first day, from a single terminal, catalogers at Ohio University in Athens, Ohio, cataloged 133 books online. Today, WorldCat comprises more than 240 million records representing more than 1.7 billion items in OCLC member libraries worldwide.”
