COUNTER1
• Launched in March 2002, COUNTER (Counting Online Usage of Networked Electronic Resources) is an international initiative designed to serve librarians, publishers and intermediaries by facilitating the recording and exchange of online usage statistics.
• COUNTER has set out to achieve this, that is, the use of these online information resources should be measured in a more consistent way.

Performance Measures
• ISO 20983: Information and Documentation – Performance Indicators for Electronic Library Services
• E-Metrics (ARL)
ISO 209831
• Is the first edition for the evaluation of electronic library services in 2003.
• In the future, ISO 20983 will be incorporated into ISO 11620.
ISO 209832
• Is composed of 5 dimensions and 14 categories in the following:– User Perception: general– Public Services: general, providing documents,
retrieving documents, lending documents, document delivery from external sources, enquiry and reference services, information searching, user education, and facilities.
– Technical Services: acquiring documents, processing documents, and cataloguing.
– Promotion of Services– User Services: deployment of staff
ISO 209833
• PIs– Percentage of Population Reached by Electronic
Services– Percentage of Expenditure on Information Provision
Spent on the Electronic Collection– No. of Documents Downloaded Per Session– Cost per Database Session– Cost Per Document Downloaded– Percentage of Rejected Sessions– Percentage of Remote OPAC Sessions– Virtual Visits as a Percentage of Total Visits
ISO 209834
• PIs– Percentage of Information Requests Submitted
Electronically– No. of User Attendances at Electronic Service
Training Lessons Per Capita– Workstation Hours Available Per Capita– Population Per Public Access Workstation– Workstation Use Rate– No. of Attendances at Formal IT and Related Training
Lessons Per Staff Member– Percentage of Library Staff Providing and Developing
Electronic Services
E-Metrics1
• This E-Metrics study was 18-month project from 2000 to 2003 and was composed of three phases as follows:– An inventory– An identification– Identifying and testing data elements
• 5 dimensions of E-Metrics Projects are proposed to measure in the following:– Resource– Use– Cost– Digital Collection– Performance
E-Metrics2
• Resource Measures: Patron Accessible Electronic Resources– No. of Electronic Full-text Journals (R1)– No. of Electronic Reference Sources (R2)– No. of Electronic Books (R3)
• Use Measures: Use of Networked Resources and Services– No. of Electronic Reference Transactions (U1)– No. of Logins (Sessions) to Electronic Databases (U2)– No. of Queries (Searches) in Electronic Databases (U3)– Items of Requested in Electronic Databases (U4)– Virtual Visits to Library’s Website and Catalog (U5)
E-Metrics3
• Cost Measures: Expenditures for Networked Resources and Related Infrastructure– Cost of Electronic Full-text Journals (C1)– Cost of Electronic Reference Sources (C2)– Cost of Electronic Books (C3)– Library Expenditures for Bibliographic Utilities,
Networks, and Consortia (C4)– External Expenditures for Bibliographic
Utilities, Networks, and Consortia (C5)
E-Metrics4
• Digital Collection Measures: Library Digitization Activities– Size of Library Digital Collection (D1)– Use of Library Digital Collection (D2)– Cost of Digital Collection Construction and Management
(D3)• Performance Measures
– Percentage of Electronic Reference Transactions of Total Reference (P1)
– Percentage of Remote Library Visits of All Library Visits (P2)
– Percentage of Electronic Books to All Monographs (P3)
Service Quality
• LibQUAL+
• Balanced Scorecard
• Best Practices
• Benchmark
LibQUAL+1
• The LibQUAL+ was initiated in Sept./Oct. 1999.
• The LibQUAL+ was developed based on SERVQUAL model.
• 3 dimensions and 22 core questions. Three dimensions are listed as below:– User Perceptions of Service Affect– Information Control– Library as Place
LibQUAL+2
• User Perceptions of Service Affect– Employees who instill confidence in users.– Giving users individual attention.
• Information Control– Making electronic resources accessible from home or office.
• Library as Place– Library space that inspires study and learning
• To examine and explain the results based on 3 ways as follows:– Gap scores (min., perceived and desired scores)– Radar chart– Bar chart
Balanced Scorecard1
• The balanced scorecard was developed in the early 1990's by Drs. Robert Kaplan and David Norton and is a new approach to strategic management.
• The balanced scorecard is a management system (not only a measurement system) that enables organizations to clarify their vision and strategy and translate them into action.
• Four Dimensions– Financial– Internal Business Processes– Learning and Growth– Customer
• Vision and Strategy
Balanced Scorecard2
Outcomes Assessment1
• The Linear Model
• The Cyclic Model
• The Spiral Swirl
• A Framework

s– YY09 BI Programs– YY10 eLearning Materials– YY11 eLearning Programs
Miscellaneous
• Web Log File
• User Behaviours and Requirements
• Collection Development
Conclusions and Suggestions1
• What are to be measuredWhat goals and objectives do library plan to perform and present for?
• What data are to be measured What data are required to achieve expected goals and objectives? What are data elements, granularity and comprehensiveness collected for?
• How to assess the data– Output Assessment– Performance Measure– Service Quality– Outcomes Assessment– Strategic Management– User Study
Conclusions and Suggestions2
• Past is more Descriptive for Internal use:– Output Assessment– Performance Measures– Service Quality
• Proactive actions are required for libraries to take right now: – Service Quality– Outcome Assessment– Analysis and Profile of User Behaviours and Require
ments– Miscellaneous: Strategic Management
Conclusions and Suggestions3
• Publishers are required to offer libraries more detailed information of the usage of electronic resources in order to establish “win-win” partnership.
• In addition to assessment/measure/evaluation, user study and collection development will be more important for libraries in the near future.
• More factors are required to take into account for subscription of electronic resources, ranging from output, performance, service, outcome, to user requirements and collection development.
