    The Ex Libris Central Discovery Index (CDI) – An Overview

    Return to menu


    Ex Libris continues to execute on its strategic plan for accelerating discovery product innovation, enhancing operational excellence, and improving customer experience. Over the past years, since Summon joined the Ex Libris organization, we have further enriched both Summon and Primo with new features, and unified content, cloud, and support operations under one organization. As a result, we have been able to create a more agile operation, introduce new services, and enhance product performance, across both products.

    Our discovery environment is changing significantly with an increasing amount of new material and material types becoming available. New ways of discovery, beyond just the one result list option, need to be supported to enable users to find the resources they need in indexes that are now far beyond the three billion records bar. We introduced over the past years new features to support discovery not only with searching but also exploration and learning. In the future we will continue to enhance such areas by creating data relationships that enable us to release more exploration paths and smart discovery services.

    As part of our discovery strategy to meet user and customer expectations in the coming years, we are creating a unified index, leveraging our existing assets. The Ex Libris Central Discovery Index (CDI) is a central, unified index that has an upgraded infrastructure and that supports both Primo and Summon. With this move, we will be able to deliver an even more robust content index and expand the services that leverage it. With CDI, you will benefit from faster update cycles, better capacity for ingestion, enhanced ranking algorithms, and a separate database to store material relations.

    At the same time, we fully recognize our customers' choice of which discovery system is the best fit for their organization, and we will continue to support both Summon and Primo as our flagship discovery products and to provide dedicated roadmaps for each product.

    What Is CDI?

    CDI is a central discovery index – leveraging existing assets - that supports both Summon and Primo and delivers enhanced discovery, streamlines library management, and provides operational efficiencies. CDI will replace the Primo Central Index and the Summon Index to give access to Ex Libris provided data. The ingestion of local data will continue to function as before.
