On May 4, the University of Alberta Libraries created the 2,000,000,000th holding record in WorldCat, marking a major milestone for this unique library resource.

For the past 40 years, libraries like yours have worked together to build, sustain and improve WorldCat. These cooperative efforts get information seekers to the answers they need, and help other libraries be more efficient.

Congratulations to you—the OCLC community—on making this great achievement possible.
