Getting the Most Out of Your E-Resources:
Measuring Success
Todd CarpenterManaging Director, NISO
March 18, 2008 NELINET Collection Services Conference
Where are we headed this afternoon?
• A bit about NISO• Overview of usage measurement of
e-resources• COUNTER & SUSHI• The application of usage data• Issues and concerns with use data• A glimpse into the future
March 18, 2008 NELINET Collection Services Conference
What is NISO?
• NISO - National Information Standards Organization
• NISO is the only ANSI-accredited organization tasked with the development of standards in the field of Information and Documentation
• Work with publishers, libraries, agents and other systems vendors to develop community consensus
• Develop wide range of standards– Paper permanence and steal shelving– Accessibility issues– Bibliographic formats and exchange– Web-based delivery, OpenURL, Metasearch, SUSHI

Big Challenges, Modest Resources
• Revenue: $900K, up 20% in 2007• Primary income: Member dues (60%)• Other income: Seminars, Publishing (20%)• New sources of revenue in 2007 - Grants
– Mellon $196K, IMLS - $24K (20%)
• Staff: 4 Professional full-time• Virtual staff: 10+ (Consultants, Partners)• 83 Voting Members, 25 LSA members as of
2007 • Maintenance Agencies: 12• Volunteers: 300+ spread out across the world
March 18, 2008 NELINET Collection Services Conference
Standards – Why should I care?• Standards accelerate production,
ordering/sales, dissemination, locating, storing and preserving information
• Key standards which NISO has developed
and helping to bring consensus around– ISSN, OpenURL, Z39.50, NCIP– In development: DOI, SUSHI, SERU, LEWG– In planning: Institutional ID, Performance
Measures, OpenURL Expansion,

Meaningless?
Certainly, there’s a lot of data
The difference between meaningless and meaningful data is APPLICATION
March 18, 2008 NELINET Collection Services Conference
The Early Days of E-Resources
Thinking back to 1998 - Many open questions
• How do you record traffic? • What is a hit? • Is a hit different than a download?• What about reloading?• What about images and links?• What should a report include?• Eventually, counting different versions of texts• How often do you need to provide stats• Traffic to abstracts, TOCs or other elements? • Content over multiple pages?
March 18, 2008 NELINET Collection Services Conference
Slow development of consensusICOLC - Guidelines for Statistical Measurement of
Usage of Web-Based Information ResourcesReleased in 1998, updated in 2000– Minimum Requirements– Data elements, timeframe, etc– Confidentiality– Access– Delivery– Definitions– Formats
National Commission on Libraries and Information Science (NCLIS) Electronic Access and Use-Related MeasuresReleased in 2001
March 18, 2008 NELINET Collection Services Conference
Toward Formalization
• ANSI/NISO Z39.7: 2004 - Information Services and Use Metrics & Statistics for Libraries and Information Providers -- Data DictionaryONLINE: www.niso.org/emetrics/current/index.html
• Technical Committee 46 - Information and Documentations, SC 8 - Statistics and Performance Indicators– ISO 2789: 2006 Information and documentation --
International library statistics– ISO 11620: 1998 Information and documentation --
Library performance indicators

Project COUNTER
COUNTER (Counting Online Usage of NeTworked Electronic Resources)
Formed in 2002Membership organization (as of 3/15/08)
• Industry Organizations - 13• Library Consortia - 62• Libraries - 84• Publishers - 66
Establishes Codes of Practice on the gathering, compiling and storage of publishing usage data
March 18, 2008 NELINET Collection Services Conference
COUNTER Codes of Practice
• Definitions• Specifications for Usage Reports
– What they should include– What they should look like– How and when they should be delivered
• Data processing guidelines• Auditing (New in 2006)• Compliance• Maintenance and development of the
Codes of Practice• Governance of COUNTER
March 18, 2008 NELINET Collection Services Conference
COUNTER: Current Codes of Practice1) Journals and databases
– Release 1 Code of Practice launched January 2003– Release 2 replaced Release 1 in January 2006– Release 3 under consideration - to include SUSHI
compliance and consortia reporting– Now a widely adopted standard by publishers and
librarians– 60%+ of Science Citation Index articles now covered
2) Books and reference works– Code of Practice for Books was launched March 2006
– Relevant usage metrics less clear than for journals– Different issues than for journals
• Direct comparisons between books less relevant• Understanding how different categories of book
are used is more relevant

Journal Report 1 Example

Need for easier access to usage data
• As a community, we need to reduce the time and effort necessary to collect, format and compile usage data
• “Time for meaningful analysis is compromised by the time required just to gather and record the statistics.”
– Median percentage of time spent on analysis is only 25 percent– More than half of the time is spent on gathering and formatting– Average number of hours spent working on usage data is 96 hours,
but ranged on the high end up to 1-2 FTEs entirely focused on data– Usage reports to help them make subscription decisions (94%) and
justify expenditures (86%) for their electronic resources

March 18, 2008 NELINET Collection Services Conference
One example of the need
One university with more than 75 online resources from which they draw usage data
They have a 80-page booklet containing the details of how to access and gather usage data!
How much time does it take not just compiling and maintaining this notebook, but even just going through it?
March 18, 2008 NELINET Collection Services Conference
Briefly: SUSHI
• Need: Simplify and automate the gathering of usage data for librarians
– Librarians spending months gathering data
• Solution– Server/Client system to exchange COUNTER
reports– Easily incorporated into usage systems (on
publisher side) or into ERM (on library side)– Client calls to server, asks for report, and
server runs the report and sends it on– Data exchange is taking place by machine
talking with machine

SUSHI: Where now, where to?
Passed unanimously by NISO membership in September, 2007
Formally approved as ANSI/NISO Z39.93:2007
Working toward broad ADOPTION• Ask that it be included in your ERM
solution• Demand your content providers become
SUSHI and COUNTER (rev 3) compliant• Talk to your vendors and your consortia

What is the most used resource?
BioOne’s most viewed article
The nest architecture of the Florida harvester ant, Pogonomyrmex badius
• Walter R. Tschinkel
“Coolest images on the net”

Link Prefectching affecting data?• Link prefetching is a browser mechanism, which
utilizes browser idle time to download or prefetch documents that the user might visit in the near future.
• Based on previous use data, the site provides a set of prefetching hints to the browser, and after the browser is finished loading the page, it begins silently prefetching specified documents and stores them in its cache.
• When the user visits a prefetched document, it can be served up quickly out of the browser's cache.– Source: Mozzila.org

User Interface Issues Affecting Data?
• How a publisher system is designed could affect reported usageFor example:
If you have to visit the HTML page to get the PDF

QuickTime™ and a decompressor
are needed to see this picture.
March 18, 2008 NELINET Collection Services Conference
Metasearch affecting data?• Metasearch engines conduct multiple
searches simultaneously• Retrieve, consolidate and ranks results
based on algorithmic and semantic analysis
• Provide users with resource selections• However, in many cases this search and
retrieve results in hits and downloads
March 18, 2008 NELINET Collection Services Conference
Applying Usage Data
Data - All facts
Information - Facts within context
Knowledge - Interrelationships among relevant facts
Wisdom - Actionable knowledge
March 18, 2008 NELINET Collection Services Conference
Basic Measures
• Cost-per use - Are we getting comparative value from this resource?
• Are my systems working?• Are there barriers to use - why are
similar products experiencing different use patterns?
• Expressing value to administration, contributors or government sponsors
March 18, 2008 NELINET Collection Services Conference
Using Usage as a Quality Measure
• The amount of traffic an item receives is separate, but valuable, metric for assessing quality
• Citation measures capture only one type of use - scholarly citation, not necessarily quality
• Teaching or clinical use is extremely valuable
March 18, 2008 NELINET Collection Services Conference
Comparing usage measuresDevelopment project underway within
COUNTER in partnership with UKSG
Goal: Derive a meaningful calculation for assessing quality through COUNTER data
Usage of items / Period of timeQuestions primarily related to the
denominator used in calculation
March 18, 2008 NELINET Collection Services Conference
Two methods for assessing quality
• Impact Factor– Established, understood and generally accepted– Funding agencies, researchers rely on its data– Limitation in the fields of scholarship it covers– Reflects value of journals to researchers, but not all users– Over-emphasis on IF distorts the behaviour of authors– Over-used, mis-used and over-interpreted
• Usage Factor– Usage-based alternative perspective– Would cover all online journals– Would reflect value of journals to all categories of user– Would be easy to understood
March 18, 2008 NELINET Collection Services Conference
What’s in store in the future• MESUR - MEtrics from
Scholarly Usage of Resources
• Mellon funded project to study assessment of the impact of scholarly communication items, and hence of scholars, with metrics that derive from usage data
Data analysis imaese from Johan Bollen
March 18, 2008 NELINET Collection Services Conference
MESUR - Some Examples
• Discerning methods of citation networks
• Describing journal usage comparisons
• Describing potential connectedness measures
• Relatedness of items based on use patterns
• “Readers who viewed this also views…”

Privacy Concerns
If you have enough data, you can pinpoint exact people
• Say you have domain expertise• You see person X looks at this article,
then that article, and onto this series of articles
• You’ll probably be able to figure who the person is and what they’re working on
March 18, 2008 NELINET Collection Services Conference
Other Areas for Development• Non-Journal content, A&I, bibliographies• Content on multiple platforms• Different versions existing on the
network• Institutional repository systems
– Limited usage tracking and consistent reporting
• Multimedia content, streaming content• Mash-ups and multi-feed content• Research data and visualization tools
