Countdown: 296 Hours Until OCLC’s 50th Birthday!

Note: Countdown time based on 4pm EDT on June 23, 2017 to Midnight EDT on July 6, 2017. 

From OCLC:

2017-06-23_15-37-39On July 6, 1967, the nonprofit Ohio College Library Center was established to create a shared electronic library for Ohio colleges and universities. Frederick Kilgour, founder and first President, had a plan to build a shared, online cataloging system that would effectively merge library catalogs through a computer network and database so that libraries could work collaboratively, save time and share resources.

What began 50 years ago as a regional computer system for 54 Ohio colleges has become OCLC, a global library cooperative that provides shared technology services, original research and community programs to over 16,000 libraries in 120 countries.


The OCLC Online Union Catalog began operation in 1971. Catalogers at Ohio University in Athens, Ohio, were first to catalog a book using the online cataloging system. That database, now known as WorldCat, is the world’s most comprehensive database of information about library collections. Today, WorldCat comprises more than 396 million records representing more than 2.5 billion titles in libraries worldwide
