Discovery Systems: Connecting the 21st Century Academic User to Content
Discovery systems couple a central index of metadata and content with a feature-rich discovery layer to help users find information. UCF's discovery service indexes over 690 million records from various sources and links users to full text over 80% of the time. Studies found it included relevant high-quality content for nursing and science papers. Embedding discovery into learning management systems reduces cognitive load for online students and simplifies accessing full text from courses. Discovery services also expose open access outputs by including them prominently.

Editor's Notes
- #2 Hello. I’m Athena Hoeppner, Electronic Resources Librarian for the University of Central Florida. I’m flattered to be here as part of the 2nd Seminar of 21ts Century University Libraries. I admit I am a bit intimidated by the topic selected for me by the seminar organizer: Digital Information Systems. It’s a big topic! It encompasses much more than could fit into an hour presentation, and much much more than I am qualified to speak about. Yet, this is a topic that is central to my work as an Electronic Resources. My goal is to leverage technology to connect users to content. In my day-to-day work I maintain several key systems directly related to that goal. Discovery services Access and authentication Link resolvers They are fast becoming the norm in academic libraries and the dominant factor in how faculty and students experience the library. This will be the focus of my talk.
- #4 This very abbreviated definition covers what I consider to be the two main aspects of a full Discovery system Pre-harvested central index Richly featured discovery layer The WSD vendors present them as a unified package, but many also sell them separately. You can mix and match. Lets take a whirlwind look at the central index and discovery layer.
- #5 Lots of different data sources are harvested into the central index Free indexes and Open Access and Full Text Libraries often include their MARC and IR Data Many publishers supply basic TOC data, abstracts, and simple subject keywords Subscription databases supply in-depth metadata BUT can be searched and/or viewed only if the WSD has a license to load the content and the library has a subscription to access the content - Mutually Licensed Content The exact deals between WSD vendors and other vendors not uniform Library can customize which databases to include No two WSD implementation alike
- #6 Search box embedded on the library home page. Possibly tabs or other ways to present search by type or source.
- #7 Discovery Layer: At a minimum, the WSD Discovery Layer Searches across the central index Presents relevancy-ranked results list Usually includes ILS Integration
- #8 There are 4 major offerings that match the definition I use, and one that offers a related service. All these vendors offer modern, richly featured discovery interfaces, but just four have a large central index of pre-harvested metadata Innovative has a discovery product that is a little different. They are not creating a web-scale central index. Instead they use web services to integrate results local library results and external indexes into a combined results set Encore Synergy partnered with EBSCO to offer EBSCO’s central index as one of the searched sources. Each vendor puts their own spin on WSD. None started with a blank slate – the built upon existing business and strengths WCL: Of course has WorldCat – the largest union catalog, ILL service, and cataloging expertise, and the FirstSearch interface EDS: Existing relationships with journal publishers, strong collection of A/I and aggregator databases, hosted full text, EBSCOhost search interface Summon: Serials Solutions, ProQuest search interface, ProQuest A/I and aggregator databases, hosted full text Primo: Aleph ILS, OPAC search system Encore: Innovative ILS, OPAC search system
- #10 My first study of our WSD content was inspired by UCF librarians who view it as a tool for early undergrads only. They doubted that OneSearch could successfully serve the needs of grad students and faculty because: It would not contain the level , the appropriate articles, with sufficient metadata and the search results would be significantly incomplete.
- #18 Searched Web of Science for Organization: University of Central Florida. Arbitrarily selected papers published years 2013, 2010, 2000, 1990, and 1980 then analyzed to select 5 most highly cited, and 5 mid-ranged cited papers. Exported all the articles from the works cited for the 10 selected papers.
- #24 Searchers do not use Discovery systems to the fullest Relevancy is absolutely key, but only gets users so far Static Relevancy criteria makes assumptions about which content is best – the assumptions may be wrong in any given situation Can the interface become responsive and influence the user make better search choices? Or prompt the user to reveal which kind of relevancy criteria are most important for their search?
- #27 Users typically don’t use all those nice tools I just covered. Users enter 1-3 search terms, then pick results from the first few screens. Relevancy ranking controls which of the hits users will see and use. Relevancy is extremely important and hard to pin down. These criteria are basically static – they don’t base the criteria or weights on user behavior or results sets. Anecdotally – ranking works pretty well but is not quite enough for the surfacing all the best results
- #40 Once published Open Access content becomes mostly indistinguishable from subscription content in library tools such as the discovery service and OpenURL resolver. The catalog, discovery services, and Journals lists include OA, but don’t highlight it Users may find and access OA without knowing it On the open web must know to seek out OA in specialized directories or host sites These sites lack in-depth indexing and only basic subject categorization
- #42 Lots of different data sources are harvested into the central index Free indexes and Open Access and Full Text Libraries often include their and IR Data Many publishers supply basic TOC data, abstracts, and simple subject keywords
