2. Library Discovery at a Crossroads
Academic libraries should “step back to reconfirm (or reconsider) their vision for discovery, to ensure that their visions connect with information-seeking practices and preferences, and to determine whether they have a viable strategy in place … to achieve their vision”
Roger Schonfeld, Ithaka S+R, 2014

3. Full Library Discovery
“Full Library Discovery” refers to discovery approaches that move beyond the retrieval of collection materials to also include local information services and content such as library websites, pathfinder information, dataset repositories, subject specialist links, and course management system content.
-- Lorcan Dempsey, OCLC, 2013

4. Challenges in Discovery
JISC 2015 report: Spotlight on the Digital; Recent Trends and Research in Scholarly Discovery Behaviour
Questions:
Should libraries care whether they are the starting point for users seeking scholarly content?
Have libraries always played a supplementary role in topical search/exploration?
Should aiding known-item discovery and delivery be the paramount concern?
How important is the Gateway function?

5. Evolution of Discovery
Over the last 30 years:
Supercatalogs with A&I services loaded
Federated search systems employing broadcast searching
Web-Scale Discovery Systems (WSDS) with metadata and full-text content aggregated into a single consolidated index
Hybrid bento style systems with information results presented in a zoned screen display with content grouped by type/material

6. Classic Web-Scale Discovery
Recent studies on WSDS have identified user issues with interpreting blended results displays in the aggregated indexes, relevancy rankings of results, and inadequate access to local library services
User emphasis on known-item searching, streamlined access to full-text
Tracking 35 Bento systems

7. Discovery at Illinois
Evolved from federated search through web-scale discovery to bento (hybrid aggregated and federated)
Bento boxes for: article results (EBSCO and Scopus), online catalog, recommended additional A&I targets (with results), subject specialists and departmental library links, other targets, Library web site results, advertising (8 partitioned areas)

8. Illinois Transaction Log Analysis

10% are one word, 24.7% > 7 words, 49.2% were <= 3 words
Large number of cut-and-paste of title, author/title, full citations
DOI searches (73 searches per day)
Heavy reliance on the article literature
Known-item searching is high = 56%
Users often have a material type in mind when they search

13. EBSCO EDS API Like: Working on:
PDF links are propagated to all target records
Rich links provided in API, e.g. to Scopus record, publisher sites, DOI links
Full citation search is outstanding
Aggregated targets include non-EBSCO A&Is
Working on:
The order of precedence of duplicate target matches
Duplicate records
The optimum number of targets
Relevancy ranking

19. Bento Observations Have Local control and customization
Features sets vary; many bento versions do not do spell checking and do not provide direct links from the bento display page to full-text
Only three employ the one-click to full-text w/p going through local link resolver
Have Local control and customization
But, requires programming/server staff and maintenance … API processing
Need for catalog item availability and direct links to ebooks
