Deep and broad coverage
Ex Libris tracks and works with the broadest types of resources, thanks to our close relationships with global and local content providers. This comprehensive approach provides users with the ability to successfully discover easy and hard-to-find content across all sources.

Stewardship of metadata
The dedicated team of professional Ex Libris librarians uses its deep expertise in metadata management to continuously aggregate, enrich, and update resources for the Central Discovery Index. Our experts and content handling processes bring together and maintain metadata records and data from all content types and available sources, treating sources equally to improve the discoverability and accessibility of online collections of content.

Authoritative and rich metadata
The scholarly resources searched through Primo contain extensive metadata which improves the delivery of relevant results through the entire collection. The level of record detail includes subject terms, controlled vocabularies, author-provided keywords, metadata from A&I sources, CrossRef DOIs, Ulrich’s peer-reviewed indicators, and more – resulting from an efficient flow of data and close collaboration with content providers.
Community engagement
Customers play a critical role in suggesting additions to the Central Discovery Index. The Ex Libris Idea Exchange Content forum provides you with opportunities to submit, review and vote on ideas to help us grow our collections to meet both the library and its customer base.
