UDiscover, the shared discovery tool of the University and National Library of the University of Debrecen, is built on the Summon discovery service, providing a single-interface search experience across library resources. The system simultaneously searches the library’s printed holdings, subscribed electronic resources, databases, as well as a portion of the University of Debrecen’s digital collections. Search results include books, e-books, scholarly articles, journals, repository documents, and Open Access content. With a user-friendly interface and a variety of filtering options, users can quickly and efficiently refine their search to find relevant information. The aim of UDiscover is to provide fast and simple access to a broad range of information required for research, teaching, and learning.
