Overview
Context
• 1995- Elsevier offered 1,100 of its journals in electronic form to subscribers
• 1997- Elsevier launches ScienceDirect
• 1998- OhioLINK Electronic Journal Center (EJC) goes live online
• 2000- 3,000 journal titles and over 1.9 million articles in the EJC
• 2009- ScienceDirect held 9 million articles, 4,700 e-books, for 11 million
researchers in over 200 countries.
• February 2009- OhioLINK & EJC system failure
• March 2009- EJC fully restored
• 2011- 15 Millionth article added to EJC
Methodology Highlights
• Why ScienceDirect?• Ability to obtain OhioLINK wide data
• Substantial number of titles
• Parallel history
• Data reviewed from 2007-2012
• Title lists reviewed for matches
• Usage analyzed per 100 titles

Initial Findings, Thoughts & Implications
• Does it even matter that users seek content at a publisher platform over a
local platform?
• Should a local platform be transformed into something that competes with a
publisher/commercial platform? Or should it be transformed into something
that better serves the remaining users? Or should it just stay the same?
• What can be learned from the EJC to enhance other types of local platforms
being developed today (institutional repositories, digital archives, data
libraries)?
