CDI (Central Discovery Index) Guide

This article provides information about the different collection types in our knowledge bases for content that is available for discovery in CDI via Primo. With single activation, collection activation (for full text and for search) is managed from Alma and SFX. Every collection that is indexed directly or via alternative coverage in CDI contains information about how it can be activated and how linking works, as well as some activation and configuration options.

This CDI collection list (Sep.9, 2023) – contains all collections that are marked in Alma as In CDI. Collections in Alma are marked as In CDI if at least 80% of the content is indexed, either from the provider directly, or via alternative data sources. For those collections that are indexed directly from the providers, such as the primary publishers, ProQuest, Gale, and many others, the coverage is 100%. In cases where we do not get the data directly from the provider, their content (as listed in the KnowledgeBase) is mapped against the entire Index, and the percentage of overlap is calculated accordingly. The provider coverage columns provides information whether a collection is indexed with metadata directly from the provider or not.

The Views List page (Configuration Menu > Discovery > Display Configuration > Configure Views) enables you to configure multiple views that can be based on institution, library, campus, and user group. Each view can have its own look-and-feel and settings (such as search profiles and services). Discovery admin permissions are needed to make changes to Primo VE display.

Scroll down to "Valid Scope Types" for more information about configuring CDI settings in your Primo view.

As part of giving content more focus, Ex Libris has launched a new Content designated section in the Knowledge Center. You can find all your content needs in one place including recorded webinars, previous newsletters, Idea Exchange information, Knowledgebases and CDI statistics and more. The KB Release Notes will also be stored in this new location, with the content corner of each product redirecting to the new location.

The Ex Libris Central Discovery Index (CDI) is a central, unified index, for scholarly and academic material worldwide. It contains over 5 billion records and many different resource types from thousands of publishers, aggregators, and repositories.
