OhioLINK Vision & Mission

Vision: Provide Ohio students, faculty, & citizens with the best academic library content to achieve their goals and aspirations.

Mission: OhioLINK creates a competitive advantage for Ohio's higher education community by cooperatively and cost-effectively acquiring, providing access to, and preserving an expanding array of print and digital scholarly resources in order to advance teaching, learning, research, and the growth of Ohio's knowledge-based economy.

Slide 4

OhioLINK: Putting the “I” in “IT” for over 20 years Shared Print Collections• 121 libraries• 50 Million Items• 600,000 items delivered per year

Shared E-Resources• Annual content purchase of $42,000,000• Millions of articles in 10,000 journals• More than 100 databases• 110,000 ebooks• And more

Technology Services• E-Journal, E-book, and

database platforms• Statewide publishing platform for

Electronic Theses and Dissertations• Management and support of major

Platforms – Central Catalog,Discovery Layer, Link Resolver

• E-book Cataloging (Metadata Services)

Slide 5

Quick History of eBooks at OhioLINK

• 2 Longstanding Packages – locally loaded in the EBC (OhioLINK Electronic Book Center)– Springer– Oxford

• 2011- 2013 eBook ITN (eBook Pilot)– Worked with YBP and ebrary on hybrid of a DDA & profile

purchasing model• Ashgate, Roman & Littlefield, Cambridge

– Picked up a Wiley package (side effect of the ITN)– Very staff intensive, both for central office and librarians

assisting in the pilot

Slide 6

Shaping OhioLINK’s eBook Strategy

• Recognized that there is no “silver bullet” • Our strategy would have to involve several approaches

• Devised a plan to start looking at data and talking with aggregators and publishers to make decisions

Slide 7

OhioLINK “eBook Bake-off”

• How we started to gather information from potential vendor partners

• Invited a group of 5 aggregators to present their platforms and content to CIRM (OhioLINK’s resource selection committee)– each vendor had an equal time slot over one day– Also invited YBP to present last to talk about how they

could augment or assist with the vendors who presented

Slide 8

Focused Data Analysis: Can We Answer Our Questions?• After bake-off, we decided to focus on how best to

pursue the purchasing of University Press eBooks for OhioLINK

• Had useful information for YBP (GOBI)• We had many questions we wanted to answer. Such as:

– Which aggregators provide the most UP titles?– Which aggregators provide the most percentage of front

list titles?– Is there any relation to what OhioLINK institutions are

purchasing in print with what we can purchase in electronic?

Slide 9

Data Sources

• Limit analysis to university press content• Look at 5 aggregators with university press content

– EBSCO– JSTOR– Project Muse– ProQuest (ebrary)– University Press Scholarship Online (Oxford)

• Focus on most-purchased content in print and already-owned electronic

Slide 10

Data SourcesData Type Source

Publisher availability per aggregator Aggregator website / from reps

Title-level availability per aggregator Aggregator website / from reps

Print output from selected publishers GOBI search output

Publishers with content in EBC EBC metadata export

To make it manageable:• Limit title-level comparison to YOP 2014• Limit publisher comparison to top 10 most-purchased university presses• Request data in spreadsheet format

Slide 11

Methodology

• Phase 1: Publisher-level analysis• Where is the publishers’ content available?• Where might previously-purchased content be available?

• Phase 2: Title-level analysis• Which titles are unique to each aggregator?• How much of print is captured electronically by aggregators?

Slide 12

Publisher Analysis

• How do we handle text data that’s just a little bit different?– Excel – Fuzzy Lookup Add-on

• http://www.microsoft.com/en-us/download/details.aspx?id=15011

• Compile master list of all publishers represented in aggregators

• Match up variations of same name (e.g. Oxford University Press, Oxford U.P., etc.)

• Result:– Side-by-side table of publishers per aggregator

Findings

• Very few publishers have content on all 5 aggregators

Slide 17

Lingering Questions

• We know we won’t get all content in one place

• Need to overcome publisher-level data issues

• How do we tell if these aggregators really cover the content we want?

Slide 18

Title-Level Analysis

• How do we match up LOTS of text data that’s just a little bit different?

• OpenRefine (formerly Google Refine)– http://openrefine.org/

– Filter title lists by most-purchased university presses– Limit to YOP 2014– Reconcile not-quite-matching text & ISBN data– Count occurrences per title

Slide 19

OpenRefine Methodology

• Combine titles lists from 5 aggregators– Reconcile not-quite-matching data– Count the number of occurrences per title

• Unique ID based on ISBN and platform• Not all provided lists had both print and eISBNs

– Link books using both print and e-ISBNs– Number of occurrences counted across both

• Group publisher name variations

Slide 24

Conclusions

• Problems:– Capture existing purchased shared electronic content – Transition (shareable) print buying patterns to (shareable)

electronic

• Solution: – Confirmed there is not a one-stop shop answer

• Investigating the use of multiple aggregators– Need to keep in mind how this will affect the usability of cross

platforms for our users

– Print is not going away• We need to think not just about an eBook solution, but take

the use of print into consideration. They are not mutually exclusive.
