Next Generation User Interfaces
NEXT GENERATION LIBRARY TECHNOLOGIES -- A
conference sponsored by the Southeastern NY
Library Resources Council
  • Delivering content and services for todays
    Web-savvy library patrons

Abstract
  • Marshall Breeding will begin the conference in
    the morning by presenting an overview of the
    developing scene in next-generation library
    catalogs.  Following an era where most libraries
    relied on the OPAC module that came with their
    ILS, today many libraries are implementing a new
    generation of library interfaces with more appeal
    to todays Web-savvy library users.  Breeding
    will talk about whats different about these new
    interfaces and give an overview of the products
    and projects to consider as libraries move away
    from the OPACs of the past to a new generation of
    library interfaces.

The unfortunate exception is the use of library
Web sites usage has dropped from 2005 to 2007.

Crowded Landscape of Information Providers on the
Web
  • 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?

Better?
9
Demand for compelling library interfaces
  • Urgent need for libraries to offer interfaces
    their users will like to use
  • Move into the current millennium
  • Powerful search capabilities in tune with how the
    Web works today
  • Meet user expectations set by other Web
    destination

10
Inadequacy of ILS OPACs
  • Online Catalog modules provided with an ILS
    subject to broad criticism as failing to meet
    expectations of growing segments of library
    patrons.
  • Not great at delivering electronic content
  • Complex text-based interfaces
  • Relatively weak keyword search engines
  • Lack of good relevancy sorting
  • Narrow scope of content

11
Disjointed approach to information and service
delivery
  • 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

12
Change underway
  • Widespread dissatisfaction with most of the
    current OPACs. Many efforts toward
    next-generation catalogs and interfaces.
  • Movement among libraries to break out of the
    current mold of library catalogs and offer new
    interfaces better suited to the expectations of
    library users.
  • Decoupling of the front-end interface from the
    back-end library automation system.
  • Eventual redesign of the ILS to be better suited
    for current library collections of digital and
    print content

13
Next-Generation Interfaces
  • Scope and Concepts

14
Working toward a new generation of library
interfaces
  • Redefinition of the library catalog
  • Traditional notions of the library catalog
    questioned
  • Better information delivery tools
  • More powerful search capabilities
  • More elegant presentation

15
Redefining the catalog
  • More comprehensive information discovery
    environments
  • Its no longer enough to provide a catalog
    limited to 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

16
Comprehensive Search Service
  • Current distributed query model of federated
    search model not adequate
  • Expanded scope of search through harvested
    content
  • Consolidated search services based on metadata
    and data gathered in advance (like OAI-PMH)
  • Problems of scale diminished
  • Problems of cooperation persist
  • Federated search currently operates as a plug-in
    component of next-gen interfaces.

17
Web 2.0 Flavorings
  • Strategic infrastructure Web 2.0
  • A more social and collaborative approach
  • Web Tools and technology that foster
    collaboration
  • Integrated blogs, wiki, tagging, social
    bookmarking, user rating, user reviews
  • Avoid Web 2.0 information silos

18
Web 2.0 supporting technologies
  • Web services
  • XML APIs
  • AJAX (asynchronous JavaScript and XML)
  • Widgets

19
The Ideal Scope for Next Gen Library Interfaces
  • Unified user experience
  • A single point of entry into all the content and
    services offered by the library
  • Print Electronic
  • Local Remote
  • Locally created Content
  • User contributed content?

20
Next Generation Interfaces
  • Functions and Features

21
Interface Features / User Experience
  • Simple point of entry
  • Optional advanced search
  • Relevancy ranked results
  • Facets for narrowing and navigation
  • Query enhancement spell check, etc
  • Suggested related results
  • Navigational bread crumbs
  • Enriched visual and textual content
  • Single Sign-on

22
Relevancy Ranking
  • Based on advanced search engines specifically
    designed for relevancy
  • Endeca, Lucene, etc
  • Web users expect relevancy ordered results
  • The good stuff should be listed first
  • Users tend not to delve deep into a result list
  • Good relevancy requires a sophisticated approach,
    including objective matching criteria
    supplemented by popularity and relatedness
    factors.

23
New Paradigm for search and navigation
  • Let users drill down through the result set
    incrementally narrowing the field
  • Faceted Browsing
  • Drill-down vs up-front Boolean or Advanced
    Search
  • gives the users clues about the number of hits in
    each sub topic
  • Ability to explore collections without a priori
    knowledge
  • Visual search tools
  • Navigational Bread crumbs
  • Select / deselect facets

24
Query / Result Enhancement
  • Did you mean? and other features to avoid No
    results found
  • Validated Spell check
  • Automatic inclusion of authorized and related
    terms
  • More like this recommendation service
  • Make the query and the response to it better than
    the query provided

25
Appropriate organizational structures
  • LCSH vs FAST (Faceted Application of Subject
    Terminology)
  • Full MARC vs Dublin Core or MODS
  • Discipline-specific thesauri or ontologies
  • tags

26
Enriched content
  • Rich visual information book jacket images,
    rating scores, etc.
  • Syndetic Solutions ICE ()
  • Amazon Web Service (AWS)
  • Recent changes in term of use seem to preclude
    use by libraries
  • Google Book Search API
  • Released March 13, 2008
  • Liberal terms of use
  • No open content approach (yet)

27
Personalization / Single Sign-on
  • Customized content and service options based on
    personal preference and profile of user
  • Persistent sign-on horizontal and vertical
  • Seamless navigation in and out of appropriate
    sub-systems
  • ILL / ILS patron requests, federated search,
    proxy services
  • Credentials follow as user navigates among Web
    site components
  • ILS / Interlibrary Loan / proxy services /
    shopping cart / etc
  • Carry sign-on into and out of institutional
    resources
  • Ability to select and save content initiate
    requests customize preferences, etc.

28
Deep search
  • Entering post-metadata search era
  • Increasing opportunities to search the full
    contents
  • Google Library Print, Google Publisher, Open
    Content Alliance, Microsoft Live Book Search,
    etc.
  • High-quality metadata will improve search
    precision
  • Commercial search providers already offer search
    inside the book
  • No comprehensive full text search for books quite
    yet
  • Not currently available through library search
    environments
  • Deep search highly improved by high-quality
    metadata
  • See Systems Librarian, May 2008 Beyond the
    current generation of next-generation interfaces
    deeper search

29
Beyond Discovery
  • Fulfillment oriented
  • Search -gt select -gt view
  • Delivery/Fulfillment much harder than discovery
  • Back-end complexity should be as seamless as
    possible to the user
  • Offer services for digital and print content

30
Library-specific Features
  • Appropriate relevance factors
  • Objective keyword ranking Library weightings
  • Circulation frequency, OCLC holdings, scholarly
    content
  • Results grouping (FRBR)
  • Collection focused (vs sales-driven)

31
Enterprise Integration
  • Ability to deliver content and services through
    non-library applications
  • Campus portal solutions
  • Courseware
  • Social networking environments
  • Search portals / Feed aggregators

32
Interoperability
  • Decoupled interface implies data synchronization
  • Mass export of catalog data
  • Hooks back into the ILS for holdings and patron
    services
  • Real-time availability

33
Architecture and Standards
  • Need to have an standard approach for connecting
    new generation interfaces with ILS and other
    repositories
  • Proprietary and ad hoc methods currently prevail
  • Digital Library Federation
  • ILS-Discovery Interface Group
  • Time to start thinking about a new generation of
    ILS better suited for current library collections
    and missions.

34
Smart and Sophisticated
  • Much more difficult than old gen OPACS
  • Not a dumbed-down approach
  • Wed library specific requirements and
    expectations with e-commerce technologies

35
Deployment and Transition
  • How will libraries Join the next generation?

36
Great Benefit, Great cost?
  • A whole new level of expense to the library to
    achieve needed automation results
  • Patron interface was previously expected to be
    part of ILS
  • Cost of ILS OPAC module very modest relative to
    new discovery products
  • Can the library community bear the cost?
  • Can the library community afford not to move
    forward?

37
Can we afford a slow Transition?
  • Deployment of older OPACs widespread
  • Were very early in the adoption cycle
  • Libraries tend to cycle to new technologies at a
    slow pace
  • Time on the Web moves quickly!
  • Urgency to move quickly
  • One year in NYC is like 7 years in LA
  • One year on the Web is like 7 years in Library
    Time
