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
The role of the information provider
– Provide integrated content specifically designed to
work within the library portal environment
– Example: ISI Web of Knowledge
Types of content sources
Native content: an organisation’s 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
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
New technologies for search integration
Traditional Boolean information retrieval paradigm has
been enhanced with:
1.
Probabilistic search engines
2.
Meta-search engines
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.)
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
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
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

ISI Web of Knowledge CrossSearch
CrossSearch form
CrossSearch database selector
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?
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 attack[ti] and 2002/03/01:2002/03/08[edat]

A new solution: federated searching with WebFeat
– Provides one search interface for all your library’s
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
®
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 couldn’t
– 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...
®
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.
®
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”
®
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 crosscollection 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.
