Resource sharing

No single library can hold every item its users may need, so libraries rely on the OCLC resource sharing network to lend and borrow resources locally, in groups, and around the world. We make it easier for libraries to support one another and their users, no matter what resource is requested.

Exceed today’s expectations, plan for the future

Building on more than 40 years of leadership in resource sharing and the world’s largest resource sharing network, we are investing in our services to better meet our members’ needs. We are bringing together the best talent, the best technology, and the best of the community to provide even greater opportunities for libraries worldwide to collaborate and share.

Our approach: Communicate, engage, be transparent

Delivering on this strategy requires ongoing involvement from the interlibrary loan (ILL) community. Through our quarterly webinars and local conferences, we discuss our plans and demonstrate the solutions as they continue to develop. We also engage with libraries of all types through our user research programs. And OCLC always strives to be transparent about our business practices and partner relations.

“Helping out other libraries...”

“The time WorldShare ILL saves me translates into helping out other libraries. I find joy in filling a request after multiple libraries before me passed due to an incorrect or incomplete citation.”

“More intuitive...”

“The whole thing is more intuitive than what we were using before. I love how easy it is to see everything in the queues… We knew this would be an improvement for our patrons and our workflow, and it has been.  We’ve been glad to be there from the start as an early adopter.”
