Summary The realm of technologies helping libraries provide access to their collections and services through their web presence continues to evolve and innovate. Index- based, or “web-scale” discovery services have become a mainstay in academic libraries in helping their users find the materials they need among the vast resources available to them. Socially oriented discovery interfaces and portal products help public and other libraries bring together a variety of service and content offerings. Breeding gives an update on the realm of these public-facing technology products and services and takes a look into the trends going forward.

Discovery in ARL Libraries http://www.librarytechnology.org/arl-discovery.pl
7
Online Catalog Books, Journals, and Media at the Title Level Not in scope: Articles Book Chapters Digital objects Scope of Search Search: Search Results ILS Data
8
Next-gen Catalogs or Discovery Interface Single search box Query tools Did you mean Type-ahead Relevance ranked results Faceted navigation Enhanced visual displays Cover art Summaries, reviews, Recommendation services Books, Journals, and Media at the Title Level Other local and open access content Not in scope: Articles Book Chapters Digital objects Scope of Search
9
Discovery Interface search model Search: Digital Collections ProQuest EBSCOhost … MLA Bibliography ABC-CLIO Search Results Real-time query and responses ILS Data Local Index MetaSearch Engine
10
Discovery from Local to Web-scale Initial products focused on interface improvements AquaBrowser, Endeca, Primo, Encore, VuFind, Civica Sorcer, Axiell Arena Mostly locally-installed software Current phase is focused on pre-populated indexes that aim to deliver Web-scale discovery Primo Central (Ex Libris) Summon (Serials Solutions) WorldCat Local (OCLC) EBSCO Discovery Service (EBSCO) Encore ES (+EDS Index)
11
Public Library Information Portal Search: Digital Collections Web Site Content Community Information … Customer- provided content Reference Sources Search Results Pre-built harvesting and indexing Consolidated Index ILS Data Aggregated Content packages Archives Usage- generated Data Customer Profile
12
Discovery services as Website Replacement Portal environment that includes customized content management service that can fulfill typical offerings on library Web sites Full integration between Web site and resource discovery (ideally) Examples: Axiell Arena Infor Iguana
13
Web-scale Index-based Discovery Search: Digital Collections Web Site Content Institutional Repositories … E-Journals Reference Sources Search Results Pre-built harvesting and indexing Consolidated Index ILS Data Aggregated Content packages (2009- present) Usage- generated Data Customer Profile Open Access
14
Web-scale Search Problem Search: Search Results Pre-built harvesting and indexing Consolidated Index ?? ? Non Participating Content Sources Non Participating Content Sources Problem in how to deal with resources not provided to ingest into consolidated index Digital Collections Web Site Content Institutional Repositories … E-Journals ILS Data Aggregated Content packages
15
Expanding the Depth of Discovery
16
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
17
Full-text Book indexing HathiTrust: 11 million volumes, 5.3 million titles, 263,000 serial titles, 3.5 billion pages HathiTrust in Discovery Indexes Primo Central (Jan 20, 2012) [previously indexed only metadata] EBSCO Discovery Service (Sept 8 2011) WorldCat Local (Sept 7, 2011) Summon (Mar 28, 2011)
18
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 Objectivity: Does relevancy reflect bias or publisher preferences
19
Challenges for Collection Coverage To work effectively, discovery services need to cover comprehensively the body of content represented in library collections What about publishers that do not participate? Is content indexed at the citation or full-text level? What are the restrictions for non-authenticated users? How can libraries understand the differences in coverage among competing services?
20
Evaluating the Coverage of Index- based Discovery Services Intense competition: how well the index covers the body of scholarly content stands as a key differentiator Difficult to evaluate based on numbers of items indexed alone. Important to ascertain now your library’s content packages are represented by the discovery service. Important to know what items are indexed by citation and which are full text Important to know whether the discovery service favors the content of any given publisher
21
Non-Cooperative Scenarios Two major players are both publishers and discovery service providers EBSCO – ProQuest ProQuest does not provide content to other discovery services EBSCO does not provide content to other discovery services Issue currently being pressed by Orbis Cascade Alliance.
22
Open Discovery Initiative NISO Work Group to Develop Standards and Recommended Practices for Library Discovery Services Based on Indexed Search Informal meeting called at ALA Annual 2011 Co-Chaired by Marshall Breeding and Jenny Walker Term: Dec 2011 – Dec 2013 http://www.niso.org/workrooms/odi/

24
ODI Project Goals: Identify … needs and requirements of the three stakeholder groups in this area of work. Create recommendations and tools to streamline the process by which information providers, discovery service providers, and librarians work together to better serve libraries and their users. Provide effective means for librarians to assess the level of participation by information providers in discovery services, to evaluate the breadth and depth of content indexed and the degree to which this content is made available to the user.

26
Social Discovery
27
A more social user experience Ratings, rankings, reviews Enhanced content Connections with the library Connections with other users Challenge: Must have critical mass of engagement to have an impact
28
Social Strategies Inherent BiblioCommons: design and infrastructure created with social flavor and features Layered or integrated ChiliFresh: integrate a third party social platform into any given library catalog or discovery service
29
Socially-powered discovery Leverage use data to increase effectiveness of discovery Usage data can identify important or popular materials to inform relevancy engines Identify related materials that may not otherwise be uncovered through keyword matching Be careful to avoid introducing bias loops
30
E-Book Integration
31
Critical concern for public libraries Most libraries offer e-book lending programs Strong demand: increasing use statistics Print lending remains vigorous
32
Commercial library e-book lending services OverDrive 3M Cloud Library Baker & Taylor: Axis 360 “Douglas County Model” Locally curated e-book collections and lending platform
33
E-book Lending Models Phase I: Link out to e-book lending service Phase II: Load MARC records in local catalog, then link out on individual titles Phase III: Discovery and lending operations performed fully within the library’s catalog or discovery environment
34
Full e-book lending Discovery of print and e-book titles and copies simultaneously E-book transactions represented within patron’s library account List of charged items, due dates Service options: renew, return, etc. Ability to check-out and download e-books into e- reader
35
Library Interfaces with e-book Integration Polaris PowerPAC BiblioCommons SirsiDynix eResource Central Innovative Interfaces: Encore ES TLC: LS2 PAC OdiloTK from OdiloTID
36
The e-book integration ecosystem E-book lending services must expose APIs Online catalog or discovery services must consume APIs and adjust interface design and business logic to accommodate discovery and lending operations Challenge: each e-book service provider’s APIs are different Response: Work toward consistent or standard suite of APIs

49
Trend Tendency toward re-alignment with management systems Alma + Primo / Primo Central Sierra + Encore WorldCat Local + WorldShare Management Services Intota + Summon
50
Counter trend Many libraries continue separate discovery strategies Open source discovery + licensed Web-scale index EBSCO Discovery Service: strategy to integrate with any back-end ILS or LSP
51
Trend Increased uptake in academic libraries of Web-scale discovery services Almost a “must-have” product as one component of overall resource discovery and dissemination strategy
52
Trend Content providers cooperate with discovery service providers for indexing in Web-scale services New content partnerships continue to be announced
53
Counter Trend A&I providers and aggregators less likely to participate Competitive issues Need to preserve the value of maintaining subscriptions
54
Trend Public libraries moving back to discovery interface associated with their ILS ILS Online Catalog modules now offer most discovery interface characteristics Examples: Most libraries using Polaris ILS use Polaris PowerPAC catalog interface. Displacing AquaBrowser or Endeca TLC libraries have largely abandoned AquaBrowser for LS2 PAC
55
Counter Trend BiblioCommons BiblioCommons is the primary discovery layer widely implemented in public libraries that continues to replace ILS online catalog modules
56
Trend Increased universe of discovery through highly-shared infrastructure Built-in resource sharing by many libraries participating in shared automation environment
57
