21. What is TERMS?
TERMS is an attempt to create an
internationally crowdsourced best practices for
electronic resource management.
Based on the electronic resources
lifecycle, each segment of the lifecycle has
been developed to give the basic techniques
used.
Workflows are shared via an open dropbox
site
22. Where is TERMS available?
TERMS is freely available from three social
media sites:
Facebook: TERMS group page
TUMBLR: http://6terms.tumblr.com/
TWITTER: @6terms
Documentation regarding the best practices
are posted to Facebook & Tumblr sites
23. Future of TERMS
Working with JISC Collections in the UK to
find the best place to openly share within
their web site environment
TERMS will be presented as a poster session
at LIBER this summer, and at various events
in 2013
TERMS will be published as an ALA Technical
Report in April 2013
24. eResource Management Lifecycle –
Selection/ Evaluation Criteria
• Relevance to research and/or curriculum needs
Content • Depth and breadth of content
• Simultaneous multiple user or single user
• User interface, response time and reliability
Access • Digital Rights Management (DRM)
• Authentication
• Support (local and vendor)
Technical • Customization
• Provision of usage statistics, cataloging records
• 1-time or Subscription
Cost • Platform/hosting fees
25. eResource Management Lifecycle –
Purchasing/ Pricing Models
Purchase/own or Lease e-content
Pay-per-view (articles)
o Library-sponsored or end-user service such as
DeepDyve
Single-user or Multiple-user
Institutional or Consortial purchases
o Shared licensing and content; discounted cost
Aggregator, “Big Deal” or Title-by-title
o Fulltext databases; Publisher eJournal collections;
Individual eJournals
User demand-driven acquisition (DDA) or
Librarian-selected eContent
26. Models are publisher-driven, in most
cases, but when given a
choice, libraries must assess which
model is most cost-effective for each e-
resource.
27. eResource Management Lifecycle –
Licensing considerations
Authorized use and users
o Limits on use or users
o Downloading and printing
o Fair Use, Inter-Library Loan
Country rights (outside of N. America)
Governing Law
o Stipulate local laws govern
Cancellation and Archival rights
o What happens to content already purchased?
Model license available at LIBLICENSE
http://liblicense.crl.edu/licensing-information/model-license/
28. eBook Demand-Driven Acquisitions -
Key Aspects
New titles identified by eBook supplier for DDA service
o Based on library-selected subject/non-subject parameters
Bibliographic records loaded to catalog for users to discover
o Creates an expanding database of relevant titles
Users can access eBook for 24-hour loan periods
Short-term loans trigger a purchase after library-defined
threshold (3 loans, 4 loans, etc.)
Automated ordering & e-invoicing of purchased eBooks
(Depends on vendor)
Expenditure data for loans and purchased available (From
vendor and eBook aggregator)
29.
30.
31. eBook Demand-Driven Acquisitions - A
Case Study
Colorado State University – July 2011
Rationale
o Declining budget for books/eBooks
o Low use of books purchased via approval plan or librarian
selections
Used existing subject/non-subject parameters for weekly
records load for new eBooks
4 short-term-loans before eBook purchase triggered
After 8 months, total US dollars spent on short-term-loans and
purchases considerably less than what would have been spent
on print approval plan shipments
Given the cost savings, library is considering broadening scope
of eBook titles available for users to discover
36. Workflow Mapping
Many institutions both in the US & UK are
mapping out their processes for various
electronic resource management workflows
Mapping workflows help to understand
workflow process overlaps in different
departments & duplications of efforts via
various management tools
43. Proactive troubleshooting strategies
Working more with vendors
Extensive cross-training
Leverage tools and technology to maximize
efficiencies
Improve/expedite loading of MARC records
Improve transparency of e-resource workflow
44. Understand | Mapping helps to outline
problems in processes.
Insight | Mapping depicts missing steps of
management.
Alignment | Mapping helps all staff in the
organization to understand what the current
workflow is.
45. Resolution of access problems often requires
working multiple angles at once:
Access: what device patrons are using, what
browsers are being employed for access, is
the patron an authorized user
Service: What library services are being used
to gain access:
OpenURL, webpages, LibGuides, LMS
50. Knowing total number of problems with any given
publisher
Have percentages for when spikes of
troubleshooting requests come in to better manage
staffing for troubleshooting
Find or distinguish trends with library management
tools like OpenURL provider and where their targets
can be improved

53. Identify efficiencies between libraries, publishers
and discovery service providers
Identify needs and requirements of stakeholder
groups
Create recommendations and tools to streamline
ways to communicate with each other
Ways of assessing:
1. participation level of info providers in services
2. breadth and depth of indexed content
3. the degree that content is available and accessible to the end users
54. Standard vocabulary
NISO Recommended practice
Data and format transfer
Communicating context rights
Level of indexing, content availability

and best practices have evolved to fulfill
and/or exceed the scope of the ERMI DD

SUSHI 12 for Instititional Identities
ONIX for Serials (SOH, SPS, SRN)
NISO should continue to encourage well-
focused ERM Standards Development
57. Workflows still a big issue
NISO should convene series of webinars in
2012 to identify common needs & best
practices
Discuss findings at future conferences to
guide further work
60. Users think, process, and manage information
different
Expect more personalization and instant gratification
Are Collaborative and multitask
Learn experimentally through trial and error rather than by
formal learning and reading
Prefer non-linear access to information
Respond better to graphic than text
Expect highly intutive interfaces and convenience
61. To assess how well the library’s resources
support the needs of its users
To demonstrate value of the library to
curriculum and research
To show Return on Investment an institution has
made in the library and its electronic resources
62. Use
• Journal Usage Statistics Portal (JUSP) – locally developed tool
• Provides single point of access to COUNTER usage reports (UK academic libraries)
• 21 publishers participating
• Automated gathering of usage data through SUSHI
• Enables report comparisons across publishers and years
Transactions
• Analysis of transaction logs measures system response times, hit rates, session
lengths, whether user is inside the library or not
Quality
• SNIP - contextual citation impact
• Impact Factor - perceived ‘prestige’ of a journal
• Eigenfactor - measure of time researchers spends with a journal
63. Make data meaningful
Gather & analyze usage over time
o Multiple years vs. one point in time to identify trends
Factor in cost
o Cost/use ratio, Cost-benefit analysis
Analyze by subject, publishers, or user type
o Variations may be meaningful and aid decision-making
Look beyond the numbers
o Barriers to use (user interface, training)
o System/network/technical issues
64. California Digital Library - Value-based strategy utilizing
objective metrics to calculate the value of scholarly journals
Used to identify titles that make a greater or lesser contribution to
the University of California’s mission of teaching, research, and
public service
Analysis for over 8,600 journals in 36 UC licensed e-journal
packages
Use of locally developed Weighted Value Algorithm by Subject
3 vectors of value encompassing 6 data metrics:
o Utility (usage and citations)
o Quality (Impact Factor;1 SNIP 2)
o Cost Effectiveness (cost per use, cost per SNIP
65. Understanding the Future: Next Wave of User Data Analysis -
ITHAKA
Analysis of JSTOR usage data led to product
enhancements
▪ Turnaways resulted in providing content that is out of
copyright freely available to users
▪ Proxy re-direct feature for users who started in Google but
weren’t authenticated even when they did have institutional
access
Analysis of usage and turnaway data by discipline
o Patterns of use for current content and archival content
o Impact have discovery services have on usage
66. Which tools are you using?
What data do you have?
How do you use it?
70. Slow response
Databases are being searched, not indexes
Ranking by relevance not possible or
problematic
Results not de-duplicated
Not all of a library’s resources could be
searched
Libraries selected which resources should be
searched—too many and search might time-out
71. Allow users to search internal and external library
resources—print & electronic—simultaneously
o Fulltext article databases
o Library OPAC
o Locally created digital collections
o Open-access content
Considerations
o Simple, single search
o Results presented quickly
o Filtering & manipulation of search results
o Customization of interface by library
o Mobile interface
72. EBSCO Discovery Service (EBSCO) - 2010
Primo Central Total Care (Ex Libris) - 2010
Summon (SerialsSolutions/ Proquest) -2009
OCLC Worldcat Local - 2009
73.
74.
75. Ecole Poytechnique Federale Lausanne (EPFL)
Parallel comparison of Summon, EBSCO Discovery, Worldcat
Local and Primo (2011)
o Original methodology included focus group with users
o Technical & set-up issues resulted in shortened evaluation by only
librarians
Looked at:
o Content & Relevance (Content gaps?)
o Search functions (user interface, advanced search)
o Results view and manipulation and subsequent result use
o User account (integration with circulation to request/hold materials)
o Administration (local expertise; vendor support)
o Professional interface (permanent URLs to content records?)
“Be realistic, demand the impossible: Comparison of 4 Discovery Tools using real data at the EPFL (Ecole Polytechnique
Federale Lausanne).” D. Aymonin, et al. http://infoscience.epfl.ch/record/172947
76. EPFL conclusion:
No one ‘winner’, each service had
strengths and weaknesses
What’s important for your library and users?
o Content focus (local collections, articles, books)
o Commercial databases (content-neutral or are some
databases excluded?)
o User interface
o Price
77. Grand Valley State University, Michigan, USA
Implemented Summon in 2009
Used Google Analytics and vendor-provided
usage data to study impact of Summon on
use of eResources
Results –
o Use of abstracting & Indexing databases, already
declining, continued to decrease
o Use of fulltext resources increased ‘dramatically.’
78. “Web‐scale discovery services represent a
dramatic change in how libraries provide
access to collections. Silos that existed
based on subject content, publisher or
content provider in many ways no longer
exist or are no longer important.”

WORK ON THIS SLIDE
Since we’re here to talk about ER&L and what happened there, I thought I’d start with looking a little at the meeting and give you a sense of what it was like to attend.

Tracks are updated by ER&L’s Program Planning committee as needed.
1997: We begin to see big products created that will have an impact on libraries. The beginning of JSTOR had a big impact on libraries move from print to electronic resources.2001: The resources are increasing for the next 4-5 years. Libraries need support in managing it all. Companies attempt to help manage e-resources. Link resolvers are created to connect citations found in one place (like an A&I db) wth paid subscritions. These were early tools in the management of e-resources. We are also seeing people creating their own local tools to get work done. Presentations on homegrown databases pop up around 2001. Colleagues from UCLA, Cornell, the University of Washington, Yale and California Digital Library began their work on creating the data elements for a E-Resources Management tool. This group came together mostly because librarians needed a way to manage license terms, not something they had to worry about before now.2003: The conversation started to move to bringing together all of these dispersed e-resources. Metasearch tools begin to appear2004: Commerical ERMS are on the market2005: ER&L begins2009: In the big research libraries, more e than p was being purchased. – big shift2010/11: discovery is the hot new thing2012: Demand driven tools – Ebooks, Get It Now from Copyright Clearance Center (CCC) complements your interlibrary loan services by providing library patrons with the immediate fulfillment of full-text articles from unsubscribed journals- 24 hours a day, 7 days a week- through a cost-effective, and easy-to-use application integrated into your ILL workflow and/or OpenURL Link Resolver. GIST - CyrilleOberlander's homegrown system (he's at SUNY Geneseo). It works with ILLiad to allow a purchasing form instead of just plain ILLFuture– an area where I see more management necessary is open access resources – keeping up with changing platforms and urls, publishers, etc.
The e-resources life cycle, attributed to OilverPesch, EBSCO
The e-resources life cycle (expanded), attributed to OilverPesch, EBSCONot easy to manage eresourcesMy talk this morning is based on parts of the life cycle
TERMS began as a discussion between Graham Stone in the UK & Jill Emery in the US and developed into a set of mechanisms for trying to gather the best practices being employed in Western Europe & the US. The lifecycle points used are slightly different than the points used by the ERM workflow committee. The points used here are: Investigate, Acquire, Implement, Evaluate, Review, Cancel/Replace.
There are six key practice components listed under each lifecycle points. To date, we've gathered workflows from at least five participants and hope to grow the workflow documents in the future.AT ER&L, Jill Emery hosted roundtable discussions on each of these topics
The discussions from ER&L and other conferences are posted in a few places.The decision to use facebook & Tumblr was made so the best practices could be relatively interactive, social, and readily available to multiple participants. To date, there are 151 facebook group members, 133 followers via twitter & 16 followers directly of the Tumblr blog.
The intent is to try to create an open wiki-version with editors from around the world to help edit the entries as suggestions & new content comes in. Graham Stone is working with JISC to figure out how to best make this happen. Jill & Graham are also working on various conference program proposals to talk more widely about the project in 2013 as well as publishing the current TERMS in April 2013.
While the list of criteria used by libraries to select/evaluate e-resources can be long, most fall into these categories. Content and Cost may be the most variable as access and technical aspects have flattened across the major content-providers (aggregators and publishers). Most major providers provide Counter-compliant usage reports and permit branding/customization, for example.
Single-user vs. multiple (some major databases still price according to number of simultaneous users – GALE’s Lit Resource or ebrary/EBSCOhost eBooks, for example.
Key clauses/terms for most e-resource licensesCountry rights, in my experience, have popped up for eBooks—akin to print eds.: some titles ‘available for sale only in the UK.’ Not so much an issue for FT databasesAt ER&L 12, we had workshops on negotiations and licensing.
There are new models for collecting and acquiring materials. One popular topic right now in the US is Demand/patron-driven acquisitions.I think it’s for a number of reasons.These are the major aspects of an eBook DDA service and workflow. Available from most major eBook suppliers (ebrary, EBL, MyiLibrary). EBSCO’s service not released yet.New titles: Non-subject parameters = format, price, audience level.2. Bibliographic records: Discovery ‘pool’ – can be loaded weekly (YBP profile) or periodically (EBL, ebrary have monthly load option)5. Automated ordering: through book vendor such as YBP vs. eBook supplier will send invoice but libraries may have to created POs manually
UNLV – budget issues, data-driven decision-making, customer-service oriented, less time for librarians to select (because of embedded lib program)Pilot PDA projectYbp/ebrary Information at point of need Already aggressive to collecting ebooks (half of approval plan was epreferred)Interesting trends:Patrons are finding the books and using themIt’s very seamlessFor staff, there was a lot of work on the tech services side at first 70-80% are tied up in short term loaning, not in buying books (same trend amongst other libraries doing PDA)Traditional collection + new business model
Colorado State – example using an approval plan through YBPPat’s results:Saved moneyFaculty library committee wants to continue print and ebookpda serviceOpening up for more titleNo frivolous use

ERM Workflow Committee presentation story – this group came out of the DLF ERMI group.Making Good on the Promise of ERM: A Standards and Best Practices Discussion PaperThis publication is the outcome of the NISO Electronic Resource Management (ERM) Data Standards and Best Practices Project, a successor to the Digital Library Federation’s Electronic Resources Management Initiative (ERMI). The project’s primary goals were to perform a “gap analysis” of standards and best practices and make recommendations on the future of the ERMI Data Dictionary. The standards review and findings focused on five categories: link resolvers and knowledge bases; the work, manifestations, and access points; cost and usage-related data; license terms; and data exchange using institutional identifiersAlso included is an evaluation of how ERM systems could improve their workflow support & shortcoming in most existing systems and a detailed workflow best practices bibliography along with a list of illustrative workflow diagrams.http://www.niso.org/news/pr/view?item_key=b93c495341167780c8cbb46a007b186e652d0492
The new generation of user think, process and manage info differently from their predecessors, all leading to changed needs and expectations.They take an active role in choosing their info providersAs customers they: expect and want more personalization and instant gratification are collaborative and mulitaskers learn experimentally through trial and error rather than by formal learning and reading prefer non-linear access to information respond better to graphic than text expect highly intuitive interfaces and convenience
Why measure?Highusage may be an indicator of demand—we may be able to infer that high-use resources are relevant to what users need/wantAlso, data-driven decision-making is more and more the norm—collection building used to be a more subjective activity. No longer can that be the case with budgetary pressures and need for accountability.
1. ‘Journal Usage Statistics Portal (JUSP) helping libraries measure use and impact’ J. Lambert Mimas, U of Manchester. ER&L 2012COUNTER-searches, sessions, downloads, turnaways (by title, month to month).2. All interesting for understanding user behavior3. SNIP: Source-Normalized Impact per Paper (SNIP) measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa.Impact factor: a measure reflecting the average number of citations to recent articles publishedEigenfactor: uses algorithms use the structure of the entire network (instead of purely local citation information) to evaluate the importance of each journal.
It’s one thing to collect data and another to actually make it meaningful“http://www.slideshare.net/kramsey/getting-the-most-out-of-your-eresources-measuring-success.” 2009Todd Carpenter, Managing Director NISO
California Digital Library - Value-based strategy utilizing objective metrics to calculate the value of scholarly journals“The strategy involves using objective metrics to calculate the value of scholarly journals and identify titles that make a greater or lesser contribution to the University’s mission of teaching, research, and public service. The value-based process is objective and quantifiable and is based on measures of utility, quality, and cost effectiveness, with a goal of alignment to UC’s user communities and programmatic needs.The CDL now uses this strategy for ongoing planning and review of its eJournal packages. Each eJournal is assigned an overall value of High, Medium Low or Very Low based on it’s score.“How much value does our institution derive from Journal X compared to other journals that we license in the same discipline?” where ‘value’ is defined as a combined measure of quality, utility, and cost-effectiveness”“Calculating scholarly journal value through objective metrics.” Feb. 13, 2012, Jacqueline Wilson & Chan Lihttp://www.cdlib.org/cdlinfo/2012/02/13/calculating-scholarly-journal-value-through-objective-metrics/
JSTOR analysis of usage-ERL 2012—analyzed turnaways and saw that many were for content that was out of copyrightAlso noticed that students coming in from outside library didn’t realize they had FT access, so proxy re-direct implemented, helping increase library usageUsage and turnaway data by discipline aids libraries in their collection development and liaison activities for those disciplines
Quote from:“Be realistic, demand the impossible: Comparison of 4 Discovery Tools using real data at the EPFL (EcolePolytechniqueFederale Lausanne).” D. Aymonin, et al. http://infoscience.epfl.ch/record/172947p.2, 1st paragraph
Federated search=slow results; results not always relevant; not all of library’s eResources may be accessed.
“Web scale discovery services for the library environment are an evolution holding great potential to easily connect researchers with the library’s vast information repository. By preharvesting and centrally indexing content sourced across multiple silos, Web scale discovery services hold the promise to fundamentally improve and streamline end user discovery and delivery of content. Such content includes physical holdings, such as books and DVDs; local electronic content, such as digital image collections and institutional repository materials; and remotely hosted content purchased or licensed by the library, such as e-books and publisher or aggregator content for thousands of full-text and abstracting and indexing resources.” J.Vaughn. “Web Scale Discovery: What & Why.” Library Technology Reports. January 2011. Vol. 47, #1. p.5-11Discovery services=faster results because indexes are being searched, not databases—harvesting of metadata
