Interlibrary Loan Study

• Compare interlibrary loan borrowing patterns
  within a consortium
• Begin with OhioLink
• Compare netLibrary holdings to titles borrowed
  through interlibrary loan

7
Collection Assessment

• Analyze and compare aggregate WorldCat holdings
  for libraries
• ARL
• Academic, non-ARL
• Public
• Identify titles and their intellectual levels,
  subjects (using conspectus), and publishers

8
User Behavior Study

• Identify how print book and eBooks are used
• Focus group interviews
• Individual interviews
• Transaction log analysis

Emerging technologies provide opportunities for
new services

• Tools and features previously available only in
  integrated systems can now be provided as 'web
  services'
• network accessible application components
• interoperable building blocks for constructing
  applications
• self-describing applications that can be
  discovered and accessed over the web by other
  applications
• Technical definition
• Web Services are a suite of protocols that define
  how requests and responses between software
  applications should be encoded transferred over
  the web

Terminology services

• Methods effective for print, unlikely to be the
  same techniques used for digital documents
• Need to determine role of knowledge organization
  (KO) resources in relation to new approaches
• Authority files
• Subject heading systems and thesauri
• Classification schemes

16
Terminology resources are currently embedded in
systems services

• OCLC Connexion
• Provides access to several KO schemes links
  among schemes
• Dewey, LCSH, Name authorities
• Automated application tools
• Harvest record creation
• Classification
• Control of names, subjects, class numbers

17
Need more flexible, modular knowledge
organization services

• For example, one set of requirements
• Automatically check name and subject authorities
• Automatically supply Dewey Decimal Classification
  numbers based on subject entries
• On-demand check of subject and name authorities
  in non-OCLC record sources
• Authorities notification service
• Improve record quality/completeness

Schema transformation services

• Accept metadata in one schema and return metadata
  in another schema

22
Names

• Accept a name and return
• Authoritative version of the name
• Cluster of related names

23
Content management
Under construction

• Make a leading contribution to the economic and
  engineering issues facing the digital
  preservation community.

24
Digital preservation

• OCLC/RLG collaboration
• Moving from a consensus making phase to an
  implementation phase
• Real economic and engineering issues being
  addressed
