Analyzing Usage Statistics of Electronic Resources Jagdish Arora Director, INFLIBNET Centre
Not everything that counts can be measured. Not everything that can be measured counts. – Einstein
Why do we measure Usage? Usage statistics provide essential evidence: for extent of usage of e-resources to showcase the trends in usage over a period of time, Patterns of usage can be helpful guide for future collection development decisions to take informed decisions regarding renewal / cancellation of resources to demonstrate value for money / return on investment
Why Collect Usage Statistics? To make best and justified use of financial resources Calculating Return on Investment (RoI) Accountability To find out emerging subject disciplines Reporting usage to administration, funding agencies, etc. Strategic planning Comparison with other libraries / institutions
Why Collect Usage Statistics? Justifications for change in document format – From print to electronics – Lesser number of users visiting library physically – Lesser no. of books being issued / Less re-shelving – Increase in usage of e-resources Bench Marking – Top-cited journals available in e-format as compare to other libraries – Results of usage of e-resources by existing libraries can serve as a bench mark for other libraries
Why Collect Usage Statistics?: Additional Information Journals that are used heavily Journals not being used at all Number of denials in case of limit of simultaneous usage Preference for formats: PDF, HTML Breach of license agreement: Heady downloads or systematic downloads; How to handle it?
Acquiring Usage Statistics Content Provider (Publishers / Database Vendors) – Some publisher do not provide usage data (eg. MathSciNet, ISID, etc.) – Data inadequate and inconsistent – Data retained on the publisher’s web site only – Inconsistency in usage not reflected – Server caching not reflected
What do libraries want from usage data? Reliable usage Report in consistent format Usage at journals titles level Usage by subject area Analyse trends over time Ready access for reporting Evidence of value for money Benchmarking (comparative usage)
Adding More Value Cost-benefit analysis and RoI Impact of usage on research output Benchmarking
Why Evaluate at the Consortia Level? Evaluation is Necessary Negotiation for renewal Cost / Benefit analysis Evaluation is Possible Relativity Comparability Generalizibility
Why Evaluate ? Why Evaluate at the Consortia Level ? Review of current & prospective contracts Continuing price escalation not sustainable Evaluate prices to consortia and members Review contracts with additional criteria Promote models for quality not just quantity Plan for future
Problems with Manual Collection of Usage Statistics The usage statistics has to be gathered manually from different publishers Each publisher has – Different formats for data and delivery – Different access methods – Different availability dates Cost has to be calculated separately Data needs to be cleaned up and aggregated manually It is a labor-intensive and cumbersome process prone to data loss and errors
Harvesting Usage Statistics using SUSHI Automated import of consortia stats Consortium can track statistics for each member Data can be retrieved across a series of dates, e.g. period of months Member logins are pre-populated The library can access all COUNTER compliant usage stats across their serials holdings The library can obtain a top level view of their most and least-viewed publishers and titles
Negotiate More Effectively With COUNTER-compliant costs-per-view in hand, negotiate with publishers to realize more realistic cost models Uncover previously hidden cost information Utilize consortium-wide data to negotiate optimal terms for the group as a whole Obtain a better understanding of our consortium members’ usage patterns and collection needs
INFLIBNET Usage Portal
Benefits of Portal for Usage Usage statistics for every e-journal package for every member institutions is automatically collected Consortia-wide data readily available to the whole group for analysis and reporting The usage data can be exposed completely or partially to member institutions / consortium Administrators

MEASURING RESEARCH OUTPUT AND IMPACT OF E-RESOURCES
Measuring Research Output The Science Citation Index (SCI), Social Science Citation Index (SSCI) and Arts and Humanities Index (A&HI) are internationally recognized database that works as a filtering mechanism as it indexes qualitative research output from selected journals. The source articles appeared in three indices for 50 first- phase universities of the Consortium was searched in blocks of five years from 1975 to with an aim to compare the research output in the last block year, i.e – A un-precedental increase in research productivity in terms of number of research articles is evident during as compared to previous block of five years, i.e to
Increase in no. of articles in past 35 Years (In block of Five Years) Increase in No. of Articles to : 22.97% to : 76.59%
