The hybrid library
"The challenge associated with the management of
the hybrid library is to encourage end-user
resource discovery and information use, in a
variety of formats and from a number of local and
remote sources, in a seamlessly integrated way.
(S. Pinfield, 1998)

• Numerous providers, disparate formats
• Local, consortial, national, international
  collaboration
• Internet, intranet, mixed mode systems
• Proprietary databases, subscriptions, full-text
• Library training materials, administrative
  information
• Enterprise solutions / The library portal
• Users need to feel a part of the solution

4
The role of the information provider

• Provide integrated content specifically designed
  to work within the library portal environment
• Example ISI Web of Knowledge

5
Types of content sources

• Native content an organisations core
  information
• Examples Library training materials electronic
  theses and dissertations
• Hosted content developed through partnerships
• Example bibliographic data from information
  vendor provided through Library system/interface
• External content from source outside the
  organization
• Example bibliographic data from information
  vendor provided through vendor system/interface

6
Types of content sources ISI example

• Native content
• Examples ISI Web of Science, Current Contents
  Connect, ISI Essential Science Indicators
• Hosted content
• Examples BIOSIS Previews, CAB ABSTRACTS ,
  INSPEC, FSTA
• External content
• Examples PubMed, Agricola, Web Collections
  (from Current Web Contents), other databases via
  WebFeat

7
New technologies for search integration

• Traditional Boolean information retrieval
  paradigm has been enhanced with
• 1. Probabilistic search engines
• 2. Meta-search engines

8
1. Probabilistic search engines

• New paradigm
• Not based on algebraic relationship of terms
• Focus on the concept behind the search terms
• Weighting of terms, applying relevance
• ISI Example
• muscatdiscovery (from Smartlogik)
• WebFeat (from WebFeat Inc.)

9
muscatdiscovery in ISI Web of Knowledge

• Current Contents eSearch
• Enter Boolean terms into Current Contents
  Connect
• Translates behind-the-scenes into
  probabilistic query
• Searches Web content automatically

• ISI CrossSearch
• Enter words, phrase, or sentence into concept
  search box
• User selects databases, editions, time frame,
  and relevance level

10
2. Meta-search engines

• For true cross-collection discovery
• Single search query to multiple content sources
• Four basic components
• Database selector
• Document selector
• Query dispatcher
• Results merger

11
Meta-search engine architecture

• Database selector
• Identify databases to be searched
• Document selector
• Determine exact items to retrieve
• Query dispatcher
• Transmit individual queries to each database
• Results merger
• Return consolidated summary results list

Document selector future possibilities

• Dynamic categorization refines search by adding
  context

• Example anthrax
• Viral mechanisms?
• Government policy?
• Alternative music group?

• Collecting metrics on different databases
• Example which databases have high return rates?

17
CrossSearch query dispatcher

• Determine translation and mapping rules
• Send query in correct syntax for each database
• Example title search on heart attack for
  current week
• Web of Science heart attack
• PubMed heart attackti and 2002/03/012002/03/0

A new solution federated searching with WebFeat

• Provides one search interface for all your
  librarys electronic resources
• Supports searching of OPACs, bibliographic
  subscription databases, full-text resources,
  electronic reference materials, proprietary
  content
• Is not meant to replace searching of individual
  scientific and scholarly databases but to provide
  an initial point of access for

• Undergraduates and novice library users who need
  a starting point
• All library users who want a quick discovery tool

24
The best federated search solution WebFeat
ISI and WebFeat, Inc. partnering to provide the
best in federated searching to Academic and
Government institutions worldwide

• What Z39.50 tried to do but couldnt
• Offers sophisticated technology including an
  extensive collection of database-specific
  translators
• Implements easily on your library portal
• Will be integrated seamlessly with ISI Web of
  Knowledge environment

Four ways in which WebFeat outshines the rest...
25
1. WebFeat is a service, not just a software
package.

• Internet-based because we use our server not
  yours
• Minimal set-up because we handle the
  implementation (loading software, configuring
  database translators, and setting
  authentication/access based on your entitlements)
• No ongoing maintenance because WebFeat regularly
  updates the database translators, and your ISI
  account manager will be your single point of
  contact for all questions, modifications, and
  problem-solving
• Compare this with competitor packages that
  require your library staff to handle all set-up,
  maintenance, and trouble-shooting.

26
2. WebFeat is fully customizable.

• Individual screen elements can be placed wherever
  you want them on the screen
• The interface reflects the look-and-feel of your
  institution, not the look-and-feel of WebFeat
• Search screens customized for each site is
  possible because of its versatile authentication
  management
• Results display can be customized to include
  special hotlinks or a database scoreboard

27
WebFeat integration with ISI Web of Knowledge
For mutual subscribers, the WebFeat system is
implemented both on your library portal and
within ISI Web of Knowledge offering two ways of
cross-collection discovery.

• Reseachers and faculty who rely on the Web of
  Science and other ISI databases start from the
  ISI Web of Knowledge homepage and are led to your
  other library resources if they choose

Conclusions

• New technologies and standards
• Help address current problems but also allow
  development of new publishing models that further
  complicate our tasks and can leave the user
  confused.
• Goal for librarians
• Organise rather than consolidate choose
  products from information leaders that offer new
  technologies for organization, searching, linking
  and personal customization.
• Goal for information providers
• Help librarians organize options for end-users
• Provide integrated products that are designed to
  work within the digital library environment and
  so satisfying their customers needs.
