1 ADVANCES IN LIBRARY DISCOVERY SERVICES The State of the Art in 2011 Marshall Breeding Director for Innovative Technology and Research Vanderbilt University Library Founder and Publisher, Library Technology Guides http://www.librarytechnology.org/ http://twitter.com/mbreeding Internet Librarian 2011 May 20, 2011

2 Abstract  Marshall Breeding will provide a look in to the next generation of library catalogs. The initial phase of next-generation catalogs extended beyond the capability of the ILS online catalog module with relevancy-based search, faceted navigation, and extended scope. The current wave of discovery systems extends search to Web-scale capacity, addressing library subscriptions of scholarly content at the article level in addition to local physical and digital collections.

3 Evolution of library collection discovery tools  Bound handwritten catalogs  Card Catalogs  Library online catalogs – OPACs  Next-Gen Catalogs / Discovery interfaces  Social Discovery  Web-scale discovery services  Comprehensive presentation layer services

4 Bound Catalog National Library of Colombia

24 Discovery from Local to Web-scale  Initial products focused on technology  AquaBrowser, Endeca, Primo, Encore, VuFind  Mostly locally-installed software  Current phase focused on pre-populated indexes that aim to deliver Web-scale discovery  Summon (Serials Solutions)  WorldCat Local (OCLC)  EBSCO Discovery Service (EBSCO)  Primo Central  Encore with Article Integration

25 Social Discovery  Builds on modernized library catalog interfaces  Strong emphasis on Web 2.0 concepts  Users invited to contribute reviews, ratings, preferences, reading lists, etc.  User-supplied data becomes part of the discovery process  Users help each other to find interesting library materials  Example: Leverage use data for a recommendation service of scholarly content based on link resolver data: Ex Libris bX service

26 Differentiation in Discovery  Products increasingly specialized between public and academic libraries  Public libraries: emphasis on engagement with physical collection  Academic libraries: concern for discovery of heterogeneous material types, especially books + articles + digital objects

27 Developments in Discovery 2011

28 Continued emphasis on Index-based search  Serials Solutions: Summon  Ex Libris: Primo Central  OCLC: WorldCat Local  EBSCO: EBSCO Discovery Service  [Innovative: Encore Synergy]

29 Adoption trends  Great interest by academic libraries in Summon, EDS, Primo Central, WorldCat Local  Public Libraries: BiblioCommons adopted by major municipal libraries and consortia  Vendor specific discovery: LS2 PAC, Enterprise, Encore, Axiel Arena, Infor Iguana  AquaBrowser currently loosing ground  New SaaS version from Serials Solutions

30 Association of Research Libraries www.librarytechnology.org/arl-discovery.pl

31 Pre-populated discovery indexes  New-generation interface  Harvested local content  ILS metadata  Institutional repositories, ETDs, Digital Collection platforms  Vendor-supplied indexes of library content  E-journals, databases, e-books Full-text and metadata corresponding to e-content subscriptions  Book collections beyond local library collections

32 The Battle of the Mega Index  Working toward comprehensive representation of potential library content: ~1 billion items  Well within the thresholds of the capacity of modern search engine technologies  Apache SOLR used by most

33 Building the Index: Business strategies  Deals with publishers and providers to expose metadata and full-text for discovery  Interesting relationship among discovery service providers  Publishing business: Serials Solutions (ProQuest), EBSCO  Technology business: Ex Libris, OCLC (?)  Serials Solutions: ProQuest content + growing array of third party content  EDS: EBSCOhost content + growing array of third party content  OCLC & Ex Libris: Indexes built entirely out of third party content

34 The Challenge for Open Source  Open source discovery interfaces:  VuFind (Villanova University)  Blacklight (University of Virginia)  No open content mega index  Discovery has shifted from primarily a technology product to a content-driven product

35 Discovery Services and Publishers  Discovery services based on a central index depend on publishers and other content providers to cooperate in providing access to metadata or full text data  Not a publishing model – Users access content through publisher site

36 What’s in the Index?  Important to understand what resources from a libraries collection components are represented or not in their discovery service  Point of differentiation in selecting a discovery service  Point of differentiation in selecting content

37 Open Discovery Initiative  Project underway to address issues related to information providers, discovery service providers, and libraries  Protocols for transfer of content  Transparency of what is transferred and indexed  Rights or restrictions on how discovery services use content  Initial meeting at ALA Annual  Proposal under consideration by NISO  “Proposed New Work Item: Standards and Best Practices for Library Discovery Services Based on Indexed Search”

38 Summon: Unilateral transparency

39 Citations / Metadata > Full Text  Citations or structured metadata provide key data to power search & retrieval and faceted navigation  Indexing full-text of content amplifies access  Important to understand depth indexing  Currency, dates covered, full-text or citation  Many other factors

40 Discovery w/Full-text Book content

41 HathiTrust

42 HathiTrust:  HathiTrust will expose SOLR index to discovery providers (Summon, Primo Central, WorldCat Local, EDS)  Introduces full-text book search into discovery services  A total of 8.4 million volumes  4.6 million books  200,000 serial titles  3 billion pages of text

43 Challenge for Relevancy  Technically feasible to index hundreds of millions or billions of records through Lucene or SOLR  Difficult to order records in ways that make sense  Many fairly equivalent candidates returned for any given query  Must rely on use-based and social factors to improve relevancy rankings

44 From Discovery to Management  Serials Solutions: Summon > Web-scale management Solution  OCLC: WorldCat Local > Web-scale management Solution  Ex Libris: Primo > Alma

45 Re-coupled Discovery?  Decoupled interfaces emerged from broken online catalogs  Poor interfaces, inadequate scope  Inefficient integration between automation and discovery platforms  New wave of more tightly integrated suites:  Alma > Primo  Web-scale Management Services > WorldCat Local  Serials Solutions Web-scale Management Solution > Summon  Still possible to decouple, but more effort, worse results

46 Integration with e-book lending services  Current environment reflects weak integration:  Library catalog populated with MARC records representing e-book collection  Library users linked into e-book vendor site  Uses ILS patron authentication for patron validation and authorization  Need to move to deeper integration with more seamless user experience
