Discovery Services: The Good, The Bad
Transcript of Discovery Services: The Good, The Bad
--Lorcan Dempsey available products : WorldCat Local, EBSCOhost Discovery Service, SerialSolutions Summon and ExLibris Primo Discovery Layer
Discovery Layer + Federated Search
OS Discovery Layer +
Central Index or Federated Search
Web-scale Discovery What is a Discovery Service? Holy Grail a fancy interface to traditional library data, often pulling from additional sources but not necessarily a central index
example: Aquabrowser an alternative to a central index; a single interface that searches multiple sources simultaneously
example: EBSCOhost Integrated Search pre-indexed, pre-aggregated database of content from external sources with (ideally) unified metadata
can include the content of article databases, journals, institutional repositories, digital collections, ebooks, monographs, open access content Reality It gets confusing another term for Discovery Service, not to be confused with web-scale management some products are really just a discovery layer with federated search
example: III Encore Synergy Key concept = Central Index Presents a Google-like library search experience
Simplifies the research process (don't have to choose where to start)
Makes the discovery and access process more efficient
Single interface for searching various collections
Wide range of content included, including some that previously might be hidden, or silo-ed
Presents facets for browse-like discovery
Search interpretation (spelling mistakes, did you mean?)
Provides fancy features and interface functionality
Direct linking to articles The Good: For our users The Good: For us Keeps the library relevant in the realm of online search
Increases usage of eresources
Provides an interface that has been externally developed and tested
Decreases the time spent "teaching the tools" The Bad: For our users The Bad: For us Not really comprehensive
Some types of searching, such as known title, might be harder
Not the best search tool for all researchers
Increased lack of understanding of "how it all works" (?)
Still behind Google in search technology
Still need to interpret holdings, format and path to access
It's still library research
Change is difficult Costs $$
Still have to maintain traditional catalog
Still have to support access to databases & articles
Lack of total control over interface
Implementation is an immense project
Change is difficult
Doesn't completely solve the problem of discovery and access The Future: Of Search The Future: For us Continuing evolution of discovery products
Everything is mobile
Search as apps and portals
Browsing remains important
Discovery service as portal to every aspect of the library, including collections, guides, services, news WorldCat Local
sync eresources and catalog records
make implementation decisions
make customization decisions
learn the tool ourselves
change our online presence
change practices regarding management of eresources & catalog records (?)
support our users In descending order, the sources teachers in our survey say students are “very likely” to use in a typical research assignment:
•Google or other online search engine (94%)
•Wikipedia or other online encyclopedia (75%)
•YouTube or other social media sites (52%)
•Their peers (42%)
•Spark Notes, Cliff Notes, or other study guides (41%)
•News sites of major news organizations (25%)
•Print or electronic textbooks (18%)
•Online databases such as EBSCO, JSTOR, or Grolier (17%)
•A research librarian at their school or public library (16%)
•Printed books other than textbooks (12%)
•Student-oriented search engines such as Sweet Search (10%) Laura Wiegand Image Sources Content Sources

Vaughan, Jason. "Investigations into Library Web-Scale Discovery Services." Information Technology and Libraries. 31.1 (2012): 32-82 Need to be more Google-like an intuitive search interface
constant improvements to search technology (relevancy, smartness)
one-click access to content
one interface for all types of content
faith in relevancy rankings
fast searching and fast results
advanced features, if you want them OS = open source
locally implemented discovery layer that can potentially harnesses a vendor supplied central index or federated search
example: Blacklight, VuFind http://www.expediteresolution.com/
http://democracyinactionblog.com/2011/08/16/the-internets/ Changes to information literacy / library instruction sessions
Collection decisions: match our content with central index or visa versa?
Impact on Interlibrary Loan
Changes to authentication? To proxy? Display of licensed material vs an open catalog?
Choices regarding full-text article resolving
Effect on eresource usage
How to serve graduate students and faculty?
Width of scoping? Us? Consortium? World? From 2012 Pew Report: "How Teens Do Research in the Digital World" Not because Google is God, but because we need to stay relevant and competitive We are not the destination of choice Things that might seem Ugly, but are just different Discovery starts the moment the user hits http://library.uncw.edu Expanded definition And ends when they know how to get the item
