1 Transparency in Discovery: Marshall Breeding http://www.librarytechnology.org/ http://twitter.com/mbreeding April 7, 2014 Issues and progress in the ecosystem of Index-based Discovery
2
Description Breeding, co-chair of the NISO Open Discovery Initiative, describes the general landscape of library resource discovery products, the trend toward web-scale, index-based services, and some of the issues that sparked this initiative to bring increased transparency and other improvements to the ecosystem involving libraries, content providers, and discovery service creators. 2

Discovery Concerns Important space for libraries and publishers Discovery brings value to library collections Discovery brings uncertainty to publishers Uneven participation diminishes impact Ecosystem dominated by private agreements Complexity and uncertainty poses barriers for participation 6
7
Heterogeneous Representations Content objects represented by –MARC Records for books and journal titles –Citation data for articles –Full text for articles –Full text for books –Abstracts and Indexing data Controlled vocabularies, related terms, abstracts, selected index terms produced by subject experts –Other metadata or enrichment
8
Discovery index issues Indexing full-text enables keyword-based relevancy Citations or structured metadata provide basic terms to support search & retrieval and faceted navigation A&I terms provide access points, relevancy indicators that cannot be reproduced algorithmically Important to understand what is indexed –Currency, dates covered, full-text or citation –Many other factors 8
9
Library Perspective Strategic investments in subscriptions Strategic investments in Discovery Solutions to provide access to their collections Expect comprehensive representation of resources in discovery indexes –Problem with access to resources not represented in index –Encourage all publishers to participate and to lower thresholds of technical involvement and clarify the business rules associated with involvement Need to be able to evaluate the coverage and performance of competing index-based discovery products
10
Collection Coverage? To work effectively, discovery services need to cover comprehensively and evenly the body of content represented in library collections What primary publishers participate? What secondary or A&I publishers 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?
11
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
12
Representation of A&I Important to understand how a discovery service incorporates A&I resources –Does it receive content from the A&I provider directly and make use of value-added terminology –If not: citations or full-text indexing of some portion of the titles represented in the A&I product –NOT the same, and possibly misleading 12
13
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 how your library’s content packages are represented by the discovery service. Important to know what items are indexed by citation, which are full text, and how A&I content is handled
14
Some Key Areas for Publishers 1.Expose content appropriately 2.Trust that access to material will be controlled consistent with subscription terms 3.“Fair” Linking 4.Materials not disadvantaged or underrepresented in library discovery implementations 5.Usage reporting

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.
31
Specific deliverables Standard vocabulary NISO Recommended Practice: –Data format & transfer –Communicating content rights –Levels of indexing, content availability –Linking to content –Usage statistics –Evaluate compliance Inform and Promote Adoption 31
32
ODI Stakeholder Survey Collected data from Sept 11 thru Oct 4, 2012 Each subgroup developed questions pertinent to it area of concern 32
33
Selected results Libraries: do you use a discovery service? –Yes: 74%, Planning to soon: 17%, No: 5%, Don’t know: 4% Smallest discoverable unit: –Component title: 9%, Article: 25%, Collective work record: 11%, All the above: 50% Linking from A&I entry: 75 prefer linking to full text on original publisher’s server 33
34
Content providers (74) Contribute data: Yes-All: 44%, Some: 48%, No: 8% –Current data: 12%, Current + back files: 85 Barriers to contributing: –IP concerns, technology, staff resources Challenges in delivery: –Complicated formats: 15%, transmission of data: 18, allocation of personnel: 23%, can’t automate: 12%, None: 20% 34
35
Issues surrounding A&I resources Concern that A&I resources not be freely available to non authenticated users and only for subscribing institutions How to “credit” A&I data that contributes to search results –Example: Index entry produced by enhancing full-text with A&I data Preservation of the value added by A&I in the discovery ecosystem 35

ODI Final Report Issued for public Comment Comment period closed November 18, 2013 36
37
Report Topics Introduction –In scope / out of scope –Terms and definitions Evolution of Discovery –Related initiatives Recommendations 37
38
General Recommendations Create oversight group Conformance checklist for: –Discovery Service Providers –Content Providers 38
39
Recommendations for Content Providers Content providers should make items available to discovery service providers. –Basic: Citations: specific metadata elements –Enhanced: additional metadata + Full-text Provide to Libraries: disclosure of participation in discovery services 39
40
Recommendations for Discovery Service Creators Disclosure of content indexed –Specific metadata fields Fair / non-biased linking –Mechanisms for libraries to choose versions preferred for linking –Annual statement regarding neutrality of linking or relevance –Provide links to A&I services when applicable Usage statistics to Publishers 40
41
Current work Next Steps Finalize document based on comments from ODI members Submit for final approval by NISO D2D Hopefully finished by the end of April 2014 41

Discovery Service Trends Progress in cooperation between content providers and discovery –ProQuest announces deals with OCLC and Ex Libris Technical development of discovery services continues –Improved methods for relevancy and tools for exploring library resources Convergence of Discovery with new Library Services Platforms 43
44
Convergence Discovery and Management solutions will increasingly be implemented as matched sets –Ex Libris: Primo / Alma –Serials Solutions: Summon / Intota –OCLC: WorldCat Local / WorldShare Platform –Except: Kuali OLE, EBSCO Discovery Service Both depend on an ecosystem of interrelated knowledge bases API’s exposed to mix and match, but efficiencies and synergies are lost 44
