   Highly abstracted model of computing
   Displaces the need for local hardware and
    software
   Provisioned on demand
   Metered use of storage and computing cycles
   Platform-as-a-service
   Storage-as-a-service

   Emerging model for library discovery and
    automation
   Increasingly dubbed “Web-scale”
   Lots of non-library Web destinations deliver
    content to library patrons
    ◦   Google Scholar
    ◦   Amazon.com
    ◦   Wikipedia
    ◦   Ask.com
   Do Library Web sites and catalogs meet the
    information needs of our users?
   Do they attract their interest?
   Print > Electronic
   Increasing emphasis on subscribed content,
    especially articles and databases
   Strong emphasis on digitizing local
    collections
   New generations of library users:
    ◦ Millennial generation
    ◦ Web savvy
    ◦ Pervasive Web 2.0 concepts
   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
   More comprehensive information discovery
    environments
   Primary search tool that extends beyond
    print resources
   Digital resources cannot be an afterthought
   Systems designed for e-content only are
    also problematic
   Forcing users to use different interfaces
    depending on type of content becoming
    less tenable
   Libraries working toward consolidated user
    environments that give equal footing to
    digital and print resources
   Bound handwritten catalogs
   Card Catalogs
   Library online catalogs – OPACs
   Discovery interfaces
   Web-scale discovery services
   A single point of entry to all the content and
    services offered by the library


               Search:
   Single search box
   Query tools
    ◦ Did you mean
    ◦ Type-ahead
   Relevance ranked results
   Faceted navigation
   Enhanced visual displays
    ◦ Cover art
    ◦ Summaries, reviews,
   Recommendation services
       Online Catalog                Discovery Layer
        ◦ Interface conventions        ◦ Modern interface
          from an earlier Web            elements
          era                          ◦ Scope: aims to
        ◦ Scope: Tied to the ILS         address broad range
          and its content                of components that
          domain                         constitute library
                                         collections




   AquaBrowser
   Ex Libris Primo
   Innovative Interfaces: Encore
   Serials Solutions: Summon (under
    development)
   SirsiDynix Enterprise
   The Library Corporation: LS2 PAC
   VUFind (open source)

◦ 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
   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
   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

                                      Pre-built harvesting
                                         and indexing
   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
   Includes full-text indexing to the fullest
    extent possible
   Indexing the full corpus of information available
    globally
       Or at least major portions
   Google aims to address all the world’s information
       Not quite comprehensive – partial harvesting of any given
        resource
   Discovery Layer Products for libraries aim to address
    all content collected by libraries:
       Print
       Remotely access electronic content: e-journals, e-books,
        databases, licensed and open access.
       Local special collections: digital and print.
   Addresses the comprehensive body of content held
    within library collections
   Comprehensive, unified
   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
   Entering post-metadata search era
   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
   Not currently available through most library
    search environments
    ◦ Will be an important feature of projects such as
      HathiTrust
   Deep search highly improved by high-quality
    metadata
   Now viewed as separate problem
   Many interdependencies
   Current model of feeding discovery systems
    from many underlying repositories
    ◦ ILS / e-journal collections / collections of digital
      objects
   Will models of resource management change
    to consolidate the repositories?
   Realign Discovery and management?
   Traditional Proprietary Commercial ILS
    ◦ Millennium, Symphony, Polaris
   Traditional Open Source ILS
    ◦ Evergreen, Koha
   Clean slate automation framework (SOA,
    enterprise-ready)
    ◦ Ex Libris URM, OLE Project
   Cloud-based automation system
    ◦ WorldCat Local (+circ, acq, license management)
   Beyond selecting one brand from an
    assortment of similar products
   Several conceptually diverse options
   Companies and projects now competing on
    innovation
