  1. Developments and Trends in the LMS and Discovery Arenas 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 26 August 2010 Stockholm Program on National Infrastructure

  2. Seminar Goal • The aim of the seminar is to create an understanding of the infrastructural challenges and to contribute to a plan of action for the future. • Library Directors and System managers will discuss different solutions of availability and management of e- resources in order to make strategic choices for the development of the infrastructure at a national level.

  3. Presentation Themes • Trends and recent developments in the library system market, • resource discovery services and resource management as indexing/knowledge bases • Creation and management of data wells for metadata • Ongoing discussion regarding options for building data wells in-house, open source or partneringwith commercial actors.

  4. Summary • development and trends in the library system market, regarding resource discovery services and resource management as indexing/knowledge bases. If I should emphasize something special, it is the question of data wells for metadata. We have been investigating the data well question in a report (plesase see below, Summary in English) and there is a discussion about building data wells in-house, open source or with commercial actors. We have also invited three commercial actors to the seminar. Not an easy question!Related is also the topic of the national catalogue LIBRIS as a local OPAC for the libraries. How can Libris work as, not only the national catalogue, but also as a local OPAC? The third topic is the future for ExLibris, Metalib/SFX in Sweden. We´re happy with SFX, but not with Metalib/federated search, how to continue? But the main focus at the seminar will be resource management/data well, although Libris and Metalib/SFX questions need to be included in the discussions.   

  5. Basic Discovery Concepts

  6. Crowded Landscape of Information Providers on the Web • Lots of non-library Web destinations deliver content to library patrons • Google Search / Google Scholar • Amazon.com • Wikipedia • Ask.com

  7. User expectations

  8. Evolution of library collection discovery tools • Bound handwritten catalogs • Card Catalogs • Library online catalogs – OPACs • Next-Gen Catalogs / Discovery interfaces • Web-scale discovery services

  9. Bound Catalog

  10. Card Catalog

  11. Online Card Catalog

  12. Web-based online catalog

  13. Next-generation Catalog

  14. Next-generation Catalog

  15. Modernized 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

  16. Web site as menu of search options

  17. Disjointed approach to information and service delivery • Silos Prevail • Books: Library OPAC (ILS module) • Articles: Aggregated content products, e-journal collections • OpenURL linking services • E-journal finding aids (Often managed by link resolver) • Local digital collections • ETDs, photos, rich media collections • Metasearch engines • All searched separately

  18. Lack of unified Web presence • User’s don’t understand the distinctions we make • Catalog? • Articles and Databases? • Digital Library? • Search our Site? • Search interfaces based on content formats or management applications • Non-library Web sites are much more unified

  19. A simple vision Search: • A single point of entry to all the content and services offered by the library • …but with precision, nuanced sophistication, and multiple dimensions

  20. Web-scale discovery

  21. Online Catalog vs. Discovery Layer • Online Catalog • Interface conventions from an earlier Web era • Scope: Tied to the ILS and its content domain • Discovery Layer • Modern interface elements • Scope: aims to address broad range of components that constitute library collections

  22. Discovery Products http://www.librarytechnology.org/discovery.pl

  23. Decoupled from ILS

  24. Social discovery • Tags, user-supplied ratings and reviews • Leverage social networking interactions to assist readers in identifying interesting materials: BiblioCommons • Leverage use data for a recommendation service of scholarly content based on link resolver data: Ex Libris bX service

  25. Deep indexing • Metadata can no longer serve as the only basis for discovery • Increasing opportunities to search the full contents • Google Library Print, Google Publisher, Open Content Alliance, government publications, etc. • High-quality metadata will improve search precision • Commercial search providers already offer “search inside the book” and searching across the full text of large book collections • Important transition to full-text book search beginning in library projects • HathiTrust indexing 6 million volumes • Must become a routine component of library discovery • Deep search highly improved by high-quality metadata

  26. Discovery product Trend • Initial products focused on technology • AquaBrowser, Endeca,Primo, Encore, VUfind • Mostly locally-installed software • Current phase focused on integrated access to both local content and remote articles to deliver Web-scale discovery. Examples: • Summon (Serials Solutions) • WorldCat Local (OCLC) • EBSCO Discovery Service (EBSCO) • Primo Central • Encore Synergy

  27. Beyond Federated search • Federated Search / Metasearch use real-time queries against multiple information targets • No centralized index – presentation of dynamic results • Shallow results -- only a few results initially fetched from each target • Difficult to calculate relevancy • Performance challenges

  28. Beyond local discovery interfaces • Pre-populated indexes • Web-scale • Exploits the full depth and breadth of library collections • Beyond the bounds of the local library’s collection • Targets the universe of objective, vetted library content

  29. Pre-populated discovery services • 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 • Includes full-text indexing to the fullest extent possible

  30. Online Catalog ILS Data Search: Search Results

  31. Federated Search ILS Data Digital Collections Search: ProQuest Search Results EBSCOhost … MLA Bibliography ABC-CLIO Real-time query and responses

  32. Discovery Interface ILS Data Digital Collections Search: Local Index ProQuest Search Results EBSCOhost MetaSearch Engine … MLA Bibliography ABC-CLIO Real-time query and responses

  33. Web-scale Search ILS Data Digital Collections Search: ProQuest EBSCOhost Search Results Consolidated Index … MLA Bibliography ABC-CLIO Pre-built harvesting and indexing

  34. Web-scale Search + Federated Search ILS Data Digital Collections Search: ProQuest … Consolidated Index Search Results MLA Bibliography ABC-CLIO Pre-built harvesting and indexing FedSearch Non-harvestable Resources

  35. Discovery  Delivery • Discovered content delivered through original repositories • Publisher agreements generally preclude exposing content for direct access • Should necessarily circumvent core role of publisher

  36. Benefits • Libraries: increased access to high-cost electronic content • Users: Easer access to research resources • Publishers: Increased impact of content products • IT perspective: advance harvesting makes more efficient use of resources than simultaneous real-time queries

  37. Toward a Large-scale National Discovery environment

  38. Obstacles and Challenges • Scaleable technology platform • Acceptable relevancy-based retrieval for large heterogeneous collections • Acquisition of data and metadata for aggregated index

  39. Opportunities • Climate more favorable to harvesting e-content for indexing • Highly scaleable, open source tools for discovery infrastructure • Lucene • SOLR • Many ongoing synergistic projects as possible collaborative partners

  40. Potential Commercial Partners • Three commercial organizations will participate in the seminar: • Ex Libris • Serials Solutions • EBSCO • Each has negotiated access to commercial content products • Paved the way for library driven projects

  41. Other similar projects

  42. Summa • State and University Library of Denmark • Locally built integrated search • Catalogs + articles • Failed to receive EU funding due to lack of guarantees to receive article data from publishers • Now Partnering with Serials Solution to use article index from Summon via API

  43. Trove • National Library of Australia • Previously called Single Business Discovery Project • Brings together many previously separate discovery systems • Built in-house at NLA • Prototype released May 2009 • Includes some full-text as well as metadata • Technology: Java, Lucene, SOLR, MySQL • Details: http://www.nla.gov.au/pub/gateways/issues/101/story01.html

  44. What about OCLC? • WorldCat: ever expanding repository of metadata • Books mostly, increasing article metadata • Focused on expanding WorldCat for broad discovery • ArticleFirst 23 million records • April 2009 agreement with EBSCO for article metadata (withdrawn?). • Quantity of article metadata apparently not on track to attain the same level of comprehensiveness as seen in Summon, EDS, Primo Central

  45. Developing the Data Well / Aggregated index • Aggregation of metadata and content • Normalization – map metadata to make indexing, facets, and presentation meaningful • De-duplication of records within and between content sources • FRBR – Collapsible groupings according to FRBR concepts: • work – expression -- manifestation – item

  46. Content sources populating the Aggregated Index • Article metadata and full text • Index views according to profile • Coordinated with local OpenURL knowledge bases • Digital Collections • LMS Metadata • Books, Microfilm, periodical titles, DVD, etc • Blending of vendor provided metadata and locally managed unique content • At the cusp of being able to represent library collections comprehensively

  47. Acquiring content for Aggregated Index • Agreements with publishers and providers of article content to libraries • Open access content • Any OAI target • Local digital collections • Relevant library catalog data • OK with OCLC record use policies when aggregated at a national level?

  48. Data Well Construction • Technical • Assembling technologies of adequate scale and capacity • Indexing, Search and retrieval • Normalizing • Business / Political • Agreements with commercial publisher to provide metadata or content • Increasing expectation from libraries to allow harvesting for discovery • (Similar to COUNTER compliance, OpenURL support) • Improved performance at delivering library end users to publisher content

  49. Relationship with OpenURL Knowledgebase • The aggregation of article-level citations and content relates to journal title-level profile and availability data in the OpenURL knowledgebase • Important source of profiling needed to deliver appropriate views of the index for different libraries.
