3. Overview

4. 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

5. 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 YearTitle Count 20071910 20082050 20092084 20102154 20112243 20122245 Number of matching titles

6. Usage per 100 titles at the Electronic Journal Center and ScienceDirect EJC Usage February 2009 Usage per 100 titles ScienceDirect: y = 5.1748x - 198939 R² = 0.4997 Electronic Journal Center y = -1.2238x + 54936 R² = 0.2033

7. Rolling 12-month average usage per 100 titles at the Electronic Journal Center and ScienceDirect Usage per 100 titles Science Direct y = 5.0881x - 196354 R² = 0.8238 Electronic Journal Center y = -1.1064x + 50314 R² = 0.6413

8. 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)?
