Interlibrary Loan StudyInterlibrary Loan Study
• Compare interlibrary loan borrowing patterns within a consortium
– Begin with OhioLink
• Compare netLibrary holdings to titles borrowed through interlibrary loan
![Page 7: OCLC Research: an update Lorcan Dempsey dempseyl@oclc.org](https://reader033.vdocuments.site/reader033/viewer/2022052510/56649e855503460f94b87733/html5/thumbnails/7.jpg)
Collection AssessmentCollection 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

User Behavior StudyUser Behavior Study
• Identify how print book and eBooks are used
– Focus group interviews
– Individual interviews
– Transaction log analysis

Emerging technologies provide opportunities for new servicesEmerging 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 servicesTerminology 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
![Page 16: OCLC Research: an update Lorcan Dempsey dempseyl@oclc.org](https://reader033.vdocuments.site/reader033/viewer/2022052510/56649e855503460f94b87733/html5/thumbnails/16.jpg)
Terminology resources are currently embedded in systems & servicesTerminology 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

Need more flexible, modular knowledge organization servicesNeed 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
