Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University of Illinois at Urbana-Champaign National Institute of Technology Silchar January 21, 2015 Library Services within the Total User Experience
2
Core Library Services Activities that support the campus research and instructional experience –Discovery gateway systems that offer “smart” search assistance that mimics the actions of a trained reference librarian –Dynamic digital environments for active engagement with students and faculty The role of the academic library; the importance of establishing key campus and external partnerships Library Services within the Total User Experience
3
Role of the Library Core values: library’s changing roles in collection development, discovery and delivery, and digital scholarship Library’s role in end-to-end lifecycle of knowledge creation and knowledge management Concept of local collection much less meaningful Re-imagineering the library
4
Discovery and Delivery Libraries at a Crossroads Roger Schonfeld (Ithaka): “this is a good moment for academic libraries to step back to reconfirm (or reconsider) their vision for discovery, to ensure that their visions connect with information-seeking practices and preferences…” Exploring three technologies: –Federated search –Web-Scale Discovery Systems (WSDS) –Hybrid Bento-style approach
5
Full Library Discovery Overarching issue is how to optimize access within the complex information landscape we live in: online catalogs, publisher full-text, institutional repositories, A&I services, local and multi-institutional digital content, learning resources, etc. Full Library Discovery – Lorcan Dempsey Not only collections but services – subject area specialists, library webpages, smart search assistance, pathfinders, *personalization, etc.
6
Search & Discovery Gateway function and full-text is King Federated search: broadcast and merge over remote information targets Web-Scale Discovery Services: single aggregated index harvested from content holders Hybrid bento-style federated search where the screen display is partitioned into tile areas Numerous libraries investigating Bento
7
Search & Discovery University of Illinois at Urbana-Champaign (UIUC) Library discovery efforts: – Easy Search federated search and recommender system – WSDS: Primo Central, 2011-2014; WorldCat Discovery, 2013-; Ebsco Discovery Service API – Bento-style search and display

University of Illinois Library Gateway Revised Gateway portal introduced in September 2007, powered by Easy Search federated search system: o Recommender and discovery system o Employs context-specific and adaptive Search Assistance mechanisms o Helps with search strategy modification and navigation o Takes users into native interfaces at point of completed search o Writes out custom transaction logs
10
Evidence-Based Services We believe in user testing and incorporating user needs in systems User behavior studies and custom transaction log data and user survey input Online Catalog user studies have been contradictory Increasing usage of Gateway as access mechanism for known-item search 10

Data Management Issues U.S. federal grant agencies require Data Management Plans: NSF, NIH, DOE The 2013 White House OSTP mandate and White House memo Need to demonstrate importance to campus of a campus-wide infrastructure for data management Multiple campus stakeholders: library, academic computing center, research offices, colleges, departments
24
UIUC Library Initiative factors There is a growing number of disciplinary and government repositories We wanted to lead the efforts for a campus- wide program Wanted to show upcoming compliance issues, dangers of current practices Approached offices of: Vice-Chancellor for Research and Provost
25
NSF Data Management Plans Data Management Plans (DMPs): required element in NSF proposals, January 2011 July 2011: the Library, working with the campus Office of Sponsored Programs and Research Administration (OSPRA) began an analysis of DMPs in submitted NSF grant proposals Currently, looked at 1,600 grants with 1,260 in the analysis.
26
Reasons for DMPs Make research data available and sharable Use of data for verification of results and reproducibility of research Federal agency can show significant return on investment to justify funding Important to know storage venues and mechanisms for sharing and reuse Use of local templates and local campus resources such as institutional repository
27
Reasons for Analysis What storage venues and mechanisms for sharing and reuse are being used? Are the PI’s using local templates and local campus resources such as the IDEALS? Is the campus in danger of losing data? Of losing grants because of compliance issues?
28
Analysis Analysis attempts to characterize and classify DMPs into categories DMPs assigned multiple categories 1,260 DMPs from July 2011 to November 2013

30
Analysis Any differences in storage venue or technologies between the unfunded proposals and the funded proposals? Any differences between the proposals from the first year and the more current proposals? Other differences in proposal categories between funded and unfunded 734 active NSF awards, $861.8 million
31
Implications and Conclusions 1.No significant differences between funded/unfunded proposals in storage venues - no advantage in specifying IDEALS or Disciplinary 2.More recent proposals suggest IDEALS and disciplinary repositories included at a significantly higher level Questions remain: what is the role of the library? The campus? The subject discipline?
32
Linking of Data and Article Literature The standards are CrossRef DOIs and DataCite DOIs: we need bi-directional links Role of publishers in data storage and linking Linking is of interest to publishers, authors, grant agancies Potential for a Linked Open Data application Potential for data repository recommender service
33
Linking of Data and Article Literature Example is search of Scopus to retrieve an article by an author or on a topic The article DOI (CrossRef DOI) is extracted and a link to DataCite using this CrossRef DOI is constructed The matches at DataCite are displayed along with their links from the DataCite DOI to the dataset results landing page/producer page
34
Follow-on Vice-Chancellor for research and Provost have funded a campus-wide Research Data Service - RDS Assist in compliance with federal agencies and assist researchers with DMPs, DOIs, storage mechanisms both short-term and preservation Develop important partnerships with campus units and national entities
35
Illinois Environmental Scan Subscribe to 200+ specialized article and report databases 65K online journals Collection budget of $15 million Online is, in many cases, the exclusive access point Have a legacy online catalog (search over metadata, holdings of books, journals, +) We operate in a distributed, heterogeneous information environment 35
36
Evidence-Based Services We believe in user testing and incorporating user needs in systems User behavior studies and custom transaction log data and user survey input Online Catalog user studies have been contradictory Increasing usage of Gateway as access mechanism for known-item search 36
37
We Do Tools and Services Debate over role of Library in “discovery” Desire for one-stop-shopping We look at custom transaction logs over Gateway and ES Advisory Committee Easy Search recommender and search assistance tool Known-item access important Problem with blended displays and full-text searching 37
38
Today’s Library Gateways Academic libraries are moving from federated search systems to web-scale discovery systems (WDS) with centralized aggregated indexing to Bento-style hybrid search and discovery WDS feature single-entry search boxes with faceted limiting operations’ is faceting useful? As we transition to WDS & Bento, understanding and supporting user search behaviors is important
39
Retrieval Issues Little use of advanced systems; facet use is moderate, about 30% Full-text search retrieval and relevancy ranking issues Large number of known-item cut-and paste searches 39
40
Web-Scale Discovery Features Hosted and in the networked Cloud Aggregated index of licensed publisher-based bibliographic content – journal articles, newspaper articles, book chapters, dissertations, and local OPAC and digital content Single entry search box Blended display format with limiting facet operations & other Web 2.0 features Central aggregated index contrasts with the federated search/broadcast search approach 40
41
Why are Libraries Embracing WDS? Rival to Google; hope to bring back users Extend the OPAC and integrate local digitized content & Institutional Repository Negative experiences with federated search/broadcast search One-stop shopping approach attractive Next Big Thing – keep up with others 41
42
The Big Issues Understanding and supporting user search behaviors is important The effectiveness of full-text search and relevancy ranking is under question Some modules (e.g. OPAC) may be better than central index search/discovery Important to distinguish between discovery features and known-item access mechanisms 42
43
Easy Search Custom Transaction Log We record user actions, system suggestions, search reformulations, and clickthroughs 2010-2011 study of 1.4 million searches and 1.5 million clickthroughs 2014 study of 1 million searches, 1.1 million clickthroughs over 10 month period May 2013 to March 2014 Initially supported by NSF and IMLS OPAC studies ambiguous results; web search engine behaviors different
44
Our Study of Custom Transaction Log Data Conducted an evidence-based study of user behavior in the Easy Search University of Illinois Gateway Looked at 1.4 million searches and 1.5 million clickthroughs performed by users in Fall 2010 and Spring 2011 semesters; now updating Our transaction log studies were supported by National Science Foundation and Institute of Museum and Library Studies

53
2014 Transaction Log Analysis Sample of 974,137 user-entered searches: – average words per query is 5.11 words – This is up from earlier studies: 3.58 words per query in 2008; 3.76 words per query in 2009; 4.33 words per query in 2011 93,642 one word, 158,054 greater than 8 words 49.6% were 3 words or less, 29.4% are 6 words or more longest search was 299 words 53
54
2014 Transaction Log Analysis 20.98% of all searches in 29.13% of all sessions used a search assistance suggestion or custom added search result link 57.2% of the 489,272 search sessions were single query sessions 6% of the sessions contain 6 or more queries, 1,157 sessions contain more than 20 queries, and 96 search sessions contain more than 50 queries 54
55
Primo Clickthrough Study May-June 2014 Primo clicks 15,068 times between 05-01-2014 and 06-21-2014. Total of 147,326 clickthroughs during that time Looked at a sample of 478 of the 15,068 searches 245 known-item searches (51.8%) and 228 topical searches (48.2%) Of the 245 known-item searches, 159 were judged successful - they brought back the expected results in the Primo first page or as the top item 55
56
Primo Clickthrough Study (2) Of the 159 ‘successful’ searches, all of them were also successful in Scopus, Ebsco, CrossRef, WorldCat Discovery, Web of Knowledge, VuFind, IShare, Google, or Google Scholar searches Removing the Google results left 9 searches that were successful in Primo but not via Scopus, Ebsco, Web of Science, CrossRef, VuFind, IShare, or WorldCat Discovery. Removing CrossRef and WorldCat Discovery resulted in 35 searches successful in Primo but not successful in Scopus, Ebsco, Web of Science, VuFind, or IShare 56
57
Primo Clickthrough Study (3) Found that CrossRef and WorldCat Discovery good at retrieving successful search results for full citation searches 48 known-item searches that were unsuccessful in Primo but successful in one of the other Easy Search targets - Scopus, Ebsco, Web of Science, CrossRef, VuFind, IShare, WorldCat Discovery, or Google/GS 57
58
Primo Clickthrough Study (4) Evaluated sample against Arizona State’s Summon. In one case, a known-item search that was unsuccessful in Primo yielded a first page match in the AZU Summon. However, there were 50 known-item searches that were successful in our Primo that were unsuccessful (item not on top or first page) in the AZU Summon 58
59
Easy Search and Bento approach user survey 120 survey results that users of Easy Search provided in October 2014 43 were daily users and 53 indicated they were weekly users 99 surveys where users provided us with comments on their Easy Search experiences. In 77, users made either a very favorable (28) or favorable comment about Easy Search 59
60
Easy Search and Bento survey (2) 91 surveys with comments about the Bento approach with 66 of these providing very favorable or favorable comments 40 users with Very favorable/favorable views of ES who also held Very Favorable/Favorable views of the Bento search 17 user surveys where ES was regarded as Very Favorable/Favorable and the Bento version was regarded as Unfavorable or Neutral 60
61
Easy Search and Bento survey (3) 21 surveys where ES was regarded as Unfavorable or Neutral and the Bento version as Very favorable/Favorable Overall, this shows a significant acceptance of the Bento search and display approach Note that one of the Bento options is to re- perform the user search in “classic” Easy Search 61
62
Bento Table Table comparing the feature sets of 17 Bento search/display implementations deployed by university libraries, including our version Number of Bento versions that do not do spell checking and do not provide direct links from the bento display page to full-text None of the others employ the one-click to full- text PDF that we do 62
