• 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)?
