ILLiad®

Interlibrary loan automation for the way you work

In keeping with OCLC’s efforts to ensure our member libraries are positioned for success, we have released Tipasa, the first cloud-based ILL management system. Over time, all ILLiad libraries will migrate to Tipasa. This process will take multiple years as we further develop Tipasa to support the complex needs of various library types. We are working closely with ILLiad users to ensure that their eventual migration improves the library user experience. For more information, review answers to frequently asked questions on the Tipasa Resources page.
