The CDI, or "Central Discovery Index" is made up of over 5 billion records of many different resource types, but most often it is used to provide more granular access to content (for example, articles and book chapters).
CDI records from articles and book chapters are submitted to Ex Libris by various vendors and because article and book chapter information is not in Alma, the CDI records are able to provide that connection.
CDI records are maintained by Ex Libris and cannot be directly updated by institutions or by FLVC. However, it is sometimes possible to correct broken CDI links by updating a journal level link or editing a collection's parameters or settings. Please report CDI linking issues to FLVC - we will investigate and open a case with Ex Libris if needed.
