The ProQuest knowledgebase is the foundation for our discovery and management solutions. We deliver more value through the most comprehensive and accurate data in the industry, our own proprietary systems, our dedicated staff, and the collaboration with our clients and partners.

Here is a brief summary of 2015 updates across the Summon® index, Ulrich’s data, and our ebooks and e-journal knowledgebase.

Summon® Index in 2015

The Summon index continues to provide the widest spectrum of content, to help facilitate discovery for students, researchers, faculty and librarians. The breadth and depth of the searchable content available through the unified index has always been unmatched within the library industry and continues to be the cornerstone of the discovery experience provided by ProQuest® to users worldwide.

Since the introduction of the Summon® service we have seen unparalleled growth in the index from year to year. Our 2015 efforts culminated in approximately 450,000,000 records being added, representing nearly 28% growth. As you can see within the chart above, 2015 was really no different than previous years, as more content continued to be ingested and made available through Summon. The growth in content added value to researcher’s ability to uncover resources during their research journey, without sacrificing ease of use, relevancy, research integrity, and content neutrality.  

Summon® clients can stay updated on all releases, enhancements and newly indexed content through the Support Center.
