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
![Page 3: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/3.jpg)
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
![Page 4: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/4.jpg)
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
![Page 5: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/5.jpg)
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.

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

Digital Scholarship Centers in Libraries• Support growing & widespread e-research and digital
scholarship• Bring together expensive technologies for use by all
campus departments• Bring together expertise to serve multiple campus
departments• Support graduate and undergraduate students who
desire to create digital projects but do not have access to tools and expertise in their department
![Page 16: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/16.jpg)
Library/Campus Partnership• Library as place, Place as service• Collaboration, e-scholarship, innovation, experiment
with new forms of scholarship and publishing • Knowledge visualization, data visualization, data
analytics, next-gen design, user interaction• Lifecycle of scholarly content. Helping the institution
become a learning organization

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
![Page 24: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/24.jpg)
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
![Page 25: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/25.jpg)
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 ofDMPs in submitted NSF grant proposals
• Currently, looked at 1,600 grants with 1,260 in the analysis.
![Page 26: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/26.jpg)
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
![Page 27: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/27.jpg)
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?
![Page 28: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/28.jpg)
Analysis• Analysis attempts to characterize and classify
DMPs into categories
• DMPs assigned multiple categories
• 1,260 DMPs from July 2011 to November 2013
![Page 29: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/29.jpg)

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
![Page 31: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/31.jpg)
Implications and Conclusions1. 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?
![Page 32: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/32.jpg)
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
![Page 33: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/33.jpg)
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
![Page 34: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/34.jpg)
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

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

![Page 36: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/36.jpg)
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
![Page 37: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/37.jpg)
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
![Page 38: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/38.jpg)
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
![Page 39: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/39.jpg)
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
![Page 40: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/40.jpg)
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
![Page 41: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/41.jpg)
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
![Page 42: Library Services within the Total User Experience: Discovery and Digital Scholarship William Mischo Grainger Engineering Library Information Center University.](https://reader038.fdocuments.us/reader038/viewer/2022110103/56649e3a5503460f94b2c22f/html5/thumbnails/42.jpg)
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

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

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
